Dye-sensitized solar cells using silicon phthalocyanine photosensitizers with pyridine anchor: Preparation, evaluation of photophysical, electrochemical, and photovoltaic properties

In this study, novel two silicon phthalocyanine photosensitizers (3PY-Si and 4PY-Si) containing pyridine groups as an electron-withdrawing and anchoring group have been prepared and chemically characterized for dye-sensitized solar cells (DSSCs). Photoelectrochemical and photovoltaic properties of the photosensitizers were evaluated. The new photosensitizers elucidated by spectroscopic and electrochemical techniques. As reported by fluorescence measurements, the silicon phthalocyanine photosensitizers exhibited slightly higher fluorescence quantum yield (phi(F) = 0.25) than the unsubstituted zinc phthalocyanine which is favorable for photophysical applications. The DSSC based on complex 3PY-Si shows the highest power conversion efficiency (PCE) of 0.53% with the J(sc), V-oc and FF values of 1.205 mA cm(-2), 0.612 V, and 0.72, respectively, in the presence of the coadsorbent. These silicon phthalocyanine photosensitizers with bulky axial pyridine substituents found to be important materials for (DSSCs) since they show strong absorption in the red region and their ligands hamper the stacking of rings. This situation prevented the formation of aggregates with a common tendency to photosensitizers on the TiO2 surface.

Metabolic engineering of Rhodococcus jostii RHA1 for production of pyridine-dicarboxylic acids from lignin

Genetic modification of Rhodococcus jostii RHA1 was carried out in order to optimise the production of pyridine-2,4-dicarboxylic acid and pyridine-2,5-dicarboxylic acid bioproducts from lignin or lignocellulose breakdown, via insertion of either the Sphingobium SYK-6 ligAB genes or Paenibacillus praA gene respectively. Insertion of inducible plasmid pTipQC2 expression vector containing either ligAB or praA genes into a Delta pcaHG R. jostii RHA1 gene deletion strain gave 2-threefold higher titres of PDCA production from lignocellulose (200-287 mg/L), compared to plasmid expression in wild-type R. jostii RHA1. The ligAB genes were inserted in place of the chromosomal pcaHG genes encoding protocatechuate 3,4-dioxygenase, under the control of inducible P-icl or P-nitA promoters, or a constitutive P-tpc5 promoter, producing 2,4-PDCA products using either wheat straw lignocellulose or commercial soda lignin as carbon source. Insertion of Amycolatopsis sp. 75iv2 dyp2 gene on a pTipQC2 expression plasmid led to enhanced titres of 2,4-PDCA products, due to enhanced rate of lignin degradation. Growth in minimal media containing wheat straw lignocellulose led to the production of 2,4-PDCA in 330 mg/L titre in 40 h, with>tenfold enhanced productivity, compared with plasmid-based expression of ligAB genes in wild-type R. jostii RHA1. Production of 2,4-PDCA was also observed using several different polymeric lignins as carbon sources, and a titre of 240 mg/L was observed using a commercially available soda lignin as feedstock.

Spectroscopic studies on antimalarial Artesunate: Raman and surface-enhanced Raman scattering and adsorption geometries of Artesunate on silver nanoparticles

In this paper we report on the Raman scattering of antimalarial artesunate, as a neutral species and as an anion in sodium salt, and on the surface-enhanced Raman scattering (SERS) of the anion adsorbed on silver nanoparticles. The vibrational assignment of the strongest Raman peaks of artesunate has been made with reference to the Raman data on artemisinin and by identifying peaks due to modes largely localized on the succinic side chain of artesunate. The structure of artesunate, as well as that of the anion, has been optimized by means of ab-initio calculations at the DFT/B3LYP/cc-pVDZ calculation level and found in good agreement with the experimental molecular geometry. The conformational minima of the flexible side chain both in the anion and in the anion complexed with Ag+ have been characterized by ab-initio methods at the same level of accuracy and eight pairs of conformers have been predicted. From these data the vibrational frequencies and Raman intensities have been obtained. This has allowed to assign the SERS spectrum of chemisorbed artesunate to conformers with nearly all-trans side chain. For these conformers the artemisinin core lies as far as approximate to 9 A from the silver ion and the active SERS modes are localized on the succinic fragment. Minor contributions to the SERS intensity are due to the di-silver complex and a more sterically hindered mono complex. It is a major conclusion of this study that the interaction of artesunate with the silver surface is exclusively through the side chain, leaving untouched the peroxide group responsible of the antimalarial activity.

Tuning Optical Properties of Re(I) Carbonyl Complexes by Modifying Push-Pull Ligands Structure

In this work, the structure-property relationship was investigated for a series of Re(I) carbonyls [ReCl(CO)(3)(R-terpy-kappa N-2)], [ReCl(CO)(3)(R-dtpy-kappa N-2)], and [ReCl(CO)(3)(R-dppy-kappa N-2)]. The studied compounds bear 2,2′:6′,2 ”-terpyridines (R-terpy), 2,6-di(thiazol-2-yl)pyridines (R-dtpy), and 2,6-di(pyrazin-2-yl)pyridines (R-dppy) functionalized with strongly electron-donating cyclic (piperidine and morpholine) and acyclic (dimethylamine, diphenylamine) amine donor attached to the central pyridine ring of the triimine skeleton via phenylene linkage. Their thermal properties were evaluated using DSC. The ground- and excited-state properties of these systems were elucidated with electrochemistry, absorption and emission spectroscopy, and density-functional theory (DFT)-based calculations. The terpy skeleton was found to efficiently stabilize the LUMO orbital, as manifested by the most negative reduction potentials for Re(I) terpyridine complexes and significant blue-shift of the absorption and emission of [ReCl(CO)(3)(R-terpy-kappa N-2)] in relation to those of Re(I) carbonyls bearing dtpy- and dppy-based ligands. Substitution of the triimines with amine substituents resulted in participation of intraligand charge-transfer (ILCT) transitions, and it was found to be beneficial for hole-transport properties of the Re(I) carbonyls. The constructed nondoped and doped single layer diodes based on Re(I) complexes emitted red light with various intensity.

Design, synthesis and anti-inflammatory activity of imidazol-5-yl pyridine derivatives as p38 alpha/MAPK14 inhibitor

P38 alpha VMAPK14 is intracellular signalling regulator involved in biosynthesis of inflammatory mediator cytokines (TNF-alpha, IL-1, IL-6, and IL-1b), which induce the production of inflammatory proteins (iNOS, NF-kappa B, and COX-2). In this study, drug repurposing strategies were followed to repositioning of a series of B-RAF(V600E) imidazol-5-yl pyridine inhibitors to inhibit P38a kinase. A group 25 reported P38a kinase inhibitors were used to build a pharmacophore model for mapping the target compounds and proving their affinity for binding in P38a active site. Target compounds were evaluated for their potency against P38a kinase, compounds 1 la and 11d were the most potent inhibitors (IC50 = 47 nM and 45 nM, respectively). In addition, compound 11d effectively inhibited the production of pminflammatory cytokines TNF-alpha, 1L-6, and 1L-1 beta in LPS-induced RAW 264.7 macrophages with IC50 values of 78.03 mu M, 17.6 nM and 82.15 nM, respectively. The target compounds were tested for their anti-inflammatory activity by detecting the reduction of Nitric oxide (NO) and prostaglandin (PGE2) production in LPS-stimulated RAW 264.7 macrophages. Compound 11d exhibited satisfied inhibitory activity of the production of PGE2 and NO with IC(50 )values of 0.29 mu M and 0.61 mu M, respectively. Molecular dynamics simulations of the most potent inhibitor 11d were carried out to illustrate its conformational stability in the binding site of P38a kinase.

An iron(ii) coordination polymer of a triazolyl tris-heterocycle showing a spin state conversion triggered by loss of lattice solvent

Solvated crystals of [FeL2][BF4](2)center dot H2O (L = 2-(1,2,4-triazol-1-yl)-6-(pyrazol-1-yl)pyridine) contain a 1D coordination polymer, [Fe(mu-L)(2){Fe(OH2)(2)L-2}][BF4](4). Two iron environments linked by kappa(1):kappa(3),mu-L ligands alternate in the chains, Fe(1) being coordinated by two tridentate L ligands and Fe(2) by four monodentate L and two water molecules. Fe(1) is low-spin in a freshly prepared crystal at 150 K, but gradually converts to a high-spin form when that crystal was measured at higher temperatures. Magnetic data imply this is triggered by loss of ca. half a lattice water molecule during the experiment, rather being a thermal spin-crossover.

Structural and electronic properties of layered nanoporous organic nanocrystals

In this work, we present the optimized geometric stacking of several layered nanoporous organic nanocrystals (NONs) and the stacking effect on their electronic structure. Hexagonal layered structures, C12H6-h2D, B6N6H6-h2D and C6N6-h2D are built from aromatic organic molecular units benzene, borazine and 1,3,5-triazine, respectively while oblique structures, C10N2H4-o2D, C8N4H2-o2D, C10P2H4-o2D and C10As2H4-o2D, are built from pyridine, 1,3-diazine, phosphinine and arsinine, respectively. Our density functional theory calculations show stacking energy profiles of NONs that are similar to graphene in both the stand-alone and bulk C12H6-h2D and B6N6H6-h2D structures while the rest of the studied layered materials deviate from the perfect AB stacking. The number of layers as well as the stacking configuration significantly influence the electronic properties of these materials. Indirect to direct band gap crossovers from the bulk to monolayers are observed in all of the NONs except in C6N6-h2D which exhibits a direct band gap in both the monolayer, isolated few-layers, and bulk. Furthermore, it is observed that the electronic nature of C10As2H4-o2D changes from a semiconducting character in the isolated monolayer to a metallic character in the bulk. The porous nature and the stability of these layered NONs combined with the electronic properties observed in this work point at them as valuable materials for potential applications in nanoelectronics and gas separation membranes, as well as deep ultraviolet optoelectronics and laser devices.

Metallo-supramolecular Crosslinked Polyurethanes

The effects of incorporating metal-binding ligands as chain extenders in polyurethane elastomers were investigated. Segmented polyurethanes based on 2 kDa poly(tetramethylene oxide) (PTMO) and 4,4-methylenebis(cyclohexyl isocyanate) were polymerized using a two-step process in which 2,6-bis(1-ethyl-5-(methoxymethyl)-1H-benzo[d]imidazol-2-yl)pyridine was added as a chain extender. The resulting polyurethanes were then metallated using stoichiometric amounts of Zn(II) metal salts with different counterions. The resulting metallopolymers have substantially improved Young’s moduli, increased failure stress, and improved thermomechanical behavior. The materials were microphase-separated into anisotropic hard domains within a PTMO matrix. Simultaneous small-angle X-ray scattering and tensile testing revealed the minority hard segment domains remain relatively intact during elongation, likely due to the strength of the metal-ligand complex.

Synthesis, characterization and surface enhanced Raman spectroscopy study of a new family of different substituted cruciform molecular systems deposited on gold nanoparticles

In this work, the adsorption and orientation on gold nanoparticles (AuNps) of a new family of cruciform systems consisting of thiophene rings and imino groups were studied. The structural modification and its influence on the adsorbate-substrate interaction were evaluated by UV-Vis spectroscopy and Surface Enhanced Raman Spectroscopy (SERS). The absence of SERS spectrum for (N,N ‘-bis(4-(trifluoromethyl)benzylidene)-2,5-di (thiophene-2-yl)-1,4-diaminobenzene) CFF shows that the inclusion of a trifluoromethyl group (-CF3) on the benzylidene fragment limits the interaction of the CFF system with the gold substrate, in contrast, to that obtained for (N, N ‘-dibenzylidene-2,5-di (thiophene-2-yl) -1,4-diaminobenzene) 2-CF and (N, N ‘-bis (4-methoxybenzylidene) -2,5-di (thiophene-2yl) -1,4-diaminobenzene) CMF, where the adsorption took place preferentially through the thiophene rings, resulting in partial quinoidization. On the other hand, the interaction for compound (N, N ‘-bis (4-methylenepyridinyl) -2,5-di (thiophene-2-yl) -1,4-diaminobenzene) CPy with the surface was conducted by means of the pyridinic fragments. The systematic modification of the bifunctional cruciform systems, with groups of different nature, makes it possible to rationalize the structural aspects that directly influence the adsorbate-substrate interaction and molecular orientation on gold substrates. These structural parameters are the basis to the development of stable molecular assemblies, which can act as basic building blocks in the manufacture of molecular switches.

Synthesis of a novel 2D zinc(ii) metal-organic framework for photocatalytic degradation of organic dyes in water

A novel 2D zinc(ii) metal-organic framework, formulated as [Zn(L)(H2O)]H2O (1) (H2L = 4-(pyridine-4-yl) phthalic acid), has been successfully obtained under solvothermal conditions. This metal-organic framework (MOF) material exhibits efficient photocatalytic activity towards the degradation of organic dyes in the absence of any photosensitizer or cocatalyst. Its catalytic performance for rhodamine B (RhB) and methyl orange (MO) degradation was superior to most reported MOFs with a degradation efficiency of 98.5% for RhB and 83.8% for MO within 120 min in the absence of H2O2, which could be attributed to its high efficiency in generating O-2(-) (an effective oxidant for the degradation of dyes). The possible mechanism of the reaction was discussed in detail. In addition, 1 shows stable catalytic efficiency after five reaction cycles, which indicates that 1 exhibits efficient catalytic activity and good reusability toward the degradation of organic dyes, enabling it to be a potential candidate for environmental governance.
