Crosslinked poly(arylene ether ketone) membrane with high anion conductivity and selectivity for non-aqueous redox flow batteries

Anion exchange membranes (AEMs) consisting of poly(arylene ether ketone) (PAEK) were synthesized and crosslinked with alkyl chains containing quaternary ammonium ions for transporting anions. These crosslinked PAEK membranes (cPAEKs) enhance not only chemical/mechanical stability but also tetrafluoroborate (BET) conductivity for operating non-aqueous redox flow batteries (RFBs). Increased quaternary ammonium moieties of cPAEKs promote a high ion exchange capacity (IEC) and an aggregation of charge clusters that allowed the connection of ion transport channels. Moreover, the chemical structure of the polymer with butyl bridges can be expected to allow ion selectivity of the membrane for BET, for realizing AEMs for operating non-aqueous RFBs. The cell performance as a battery is investigated with improved cell efficiencies of 92%, 90% and 81% for coulombic efficiency (CE), voltage efficiency (VE) and energy efficiency (EE) at a current density of 1 mA cm(-1), respectively.

Direct comparison of dithienosilole and dithienogermole as pi-conjugated linkers in photosensitizers for dye-sensitized solar cells

Dithienosilole (DTS) and dithienogermole (DTG) are useful building units of pi -conjugated organic materials. In the present work, donor-pi -acceptor (D-pi -A) dyes with bis(dihexyloxyphenyl)aminophenyl, DTS or DTG, and pyridine or cyanoacrylic acid as the donor (D), the pi -conjugated linker (pi), and the acceptor (A) units, respectively, were prepared and their optical properties were investigated. The D-pi -A dyes exhibited strong absorption in the visible region, indicating efficient intramolecular donor-acceptor interaction. The addition of trifluoroacetic acid to solutions of pyridine-containing dyes led to red-shifts of the absorption bands as a result of pyridinium salt formation. Similar red-shifts were observed for cyanoacrylic acid dyes, which were due to the enhanced formation of neutral dyes relative to the separated ion pairs. The D-pi -A dyes, however, showed similar absorption spectra when attached to the TiO2 surface, indicating that the dye-TiO2 electronic interaction was rather weak. In contrast to the finding that these dyes exhibited similar optical properties regardless of the pi -linker (i.e., DTS or DTG), dye-sensitized solar cells (DSSCs) based on DTG-containing dyes exhibited superior performance compared to those based on DTS-containing dyes. Electrochemical impedance spectroscopy measurements supported the higher performance of the DSSCs with DTG-containing dyes.

Discovery of novel HIV-1 integrase-LEDGF/p75 allosteric inhibitors based on a pyridine scaffold forming an intramolecular hydrogen bond

We have discovered HIV-1 novel integrase-LEDGF/p75 allosteric inhibitors (INLAIs) based on a pyridine scaffold forming an intramolecular hydrogen bond. Scaffolds containing a pyridine moiety have been studied extensively and we have already reported that substituents extending from the C1 position contributed to the antiviral potency. In this study, we designed a new pyridine scaffold 2 with a substituent at the C1 position. Interestingly, during attempts at optimization, we found that the direction of the C1 substituents with an intramolecular hydrogen bond contributed to the antiviral potency. Compound 34f exhibited better antiviral potency against WT and the T174I mutant (EC50 (WT) = 6.6 nM, EC50 (T174I) = 270 nM) than BI 224436 (EC50 (WT) = 22 nM, EC50 (T174I) > 5000 nM).

Synergistic Effect of Fluorinated Passivator and Hole Transport Dopant Enables Stable Perovskite Solar Cells with an Efficiency Near 24%

Long-term durability is critically important for the commercialization of perovskite solar cells (PSCs). The ionic character of the perovskite and the hydrophilicity of commonly used additives for the hole-transporting layer (HTL), such as lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) and tert-butylpyridine (tBP), render PSCs prone to moisture attack, compromising their long-term stability. Here we introduce a trifluoromethylation strategy to overcome this drawback and to boost the PSC’s solar to electric power conversion efficiency (PCE). We employ 4-(trifluoromethyl)benzylammonium iodide (TFMBAI) as an amphiphilic modifier for interfacial defect mitigation and 4-(trifluoromethyl)pyridine (TFP) as an additive to enhance the HTL’s hydrophobicity. Surface treatment of the triple-cation perovskite with TFMBAI largely suppressed the nonradiative charge carrier recombination, boosting the PCE from 20.9% to 23.9% and suppressing hysteresis, while adding TFP to the HTL enhanced the PCS’s resistance to moisture while maintaining its high PCE. Taking advantage of the synergistic effects resulting from the combination of both fluoromethylated modifiers, we realize TFMBAI/TFP-based highly efficient PSCs with excellent operational stability and resistance to moisture, retaining over 96% of their initial efficiency after 500 h maximum power point tracking (MPPT) under simulated 1 sun irradiation and 97% of their initial efficiency after 1100 h of exposure under ambient conditions to a relative humidity of 60-70%.

Insight into Chemical Reduction and Charge Storage Mechanism of 2,2 ‘-Dipyridyl Disulfide toward Stable Lithium-Organic Battery

In lithium-organic batteries, organic cathode materials could dissolve in a liquid electrolyte and diffuse through the porous separator to the active lithium-metal anode, resulting in cycling instability. However, 2,2’-dipyridyl disulfide (PyDS) can be cycled 5 times better than diphenyl disulfide (PDS) although both are soluble. We believe this is related to their reactivity with lithium (Li-0). Herein, we investigate the chemical reduction of PyDS by lithiated carbon paper (Li-CP) in ether electrolyte. It is found that only 6.3% of PyDS was reduced by Li-CP after 10 days, unlike PDS. Experimental and computational results show that PyDS molecules are ionized by lithium ions of lithium salts delocalizing the charge on pyridine rings of PyDS, which can momentarily store Li-0, thus keeping the S-S bond inert in chemical reaction with Li-0.This finding is successfully utilized in a membrane-free redox flow battery with PyDS catholyte, showing long cycle life with high energy density and energy efficiency. This work reveals the interesting charge storage mechanism and the different activity of organodisulfides toward electrochemical reduction and chemical reduction due to the organic groups, which can provide guidance for the design of stable lithium-organic batteries.

Stacking interactions of borazine: important stacking at large horizontal displacements and dihydrogen bonding governed by electrostatic potentials of borazine

Potential energy surfaces of borazine-benzene and borazine-borazine stacking interactions were studied by performing DFT, CCSD(T)/CBS and SAPT calculations. The strongest borazine-benzene stacking was found in a parallel-displaced geometry, with a CCSD(T)/CBS interaction energy of -3.46 kcal mol(-1). The strongest borazine-borazine stacking has a sandwich geometry, with a CCSD(T)/CBS interaction energy of -3.57 kcal mol(-1). The study showed that borazine forms significant stacking interactions at large horizontal displacements (over 4.5 angstrom), with energies of -2.20 kcal mol(-1) for the borazine-benzene and -1.96 kcal mol(-1) for the borazine-borazine system. The strength of interactions and their geometrical preferences can be rationalized by observing the electrostatic potentials of borazine and benzene, which is in agreement with SAPT analysis showing that electrostatics is the most important energy component for borazine stacking. All the interactions found in crystal structures of borazine and related compounds were identified either as potential curve minima or the geometries obtained from their optimizations. We also report a new dihydrogen bonding dimer with a CCSD(T)/CBS interaction energy of -2.37 kcal mol(-1), which is encountered in the borazine crystal structures and enables the formation of additional simultaneous interactions that contribute to the overall stability of the crystals.

Surface-enhanced Raman scattering as a tool to study cationic surfactants exhibiting low critical micelle concentration

The collection of surface-enhanced Raman scattering (SERS) by silver nanocolloids was used to identify the critical micelle concentration (CMC) of three cationic surfactants in 0.5-M NaCl solutions: hexadecyltrimethylammonium bromide, dodecyltrimethylammonium bromide, and benzalkonium chloride. Despite structural similarity between the three test surfactans, differences of the shape and size of the respective micelles affected the corresponding SERS signals. The CMC values determined by this method agreed with the respective values measured by conventional methods, including fluorescence probing and electrical conductivity measurements. The potential for the application of SERS technique for low CMC determination without surface modification of silver nanoparticles by a Raman-active molecule was also demonstrated.

Mixed-ligand complexes of ampicillin derived Schiff base ligand and Nicotinamide: Synthesis, physico-chemical studies, DFT calculation, antibacterial study and molecular docking analysis

A novel series of mixed-ligand complexes of the type, [ML1(L-2)(3)]Cl-x [M= Cr(III), Fe(III), Co(II),Ni(II), Cu(II), Cd(II) and Hg(II), n = 2, 3], was synthesized using Schiff base (HL1) as main ligand, nicotinamide (L-2) as secondary ligand, and the corresponding metal ions in 1:3:1 molar ratio. The main ligand, HL1 was prepared by the interaction of ampicillin drug and 4-chlorobenzophenone. The synthesized mixed ligand complexes were characterized by elemental analysis, UV-Vis, FT-IR, H-1-NMR, C-13-NMR and TG/DTG studies. In the mixed-ligand complexes, the Schiff base ligand, HL1 showed coordination to the central metal ion in tridentate manner via azomethine nitrogen, beta-lactam ring oxygen and deprotonated carboxylic oxygen atoms, whereas the secondary ligand L-2 (nicotinamide, Nam) coordinated through pyridine nitrogen atoms. The synthesized complexes exhibited significant antimicrobial activity when evaluated against P. pseudomonas, E. coli, S. aureus and B. subtilis microbes. The DFT calculations were also carried out to ascertain the bonding insights into the structure. In addition, molecular docking analysis was performed carried out to know the interactions between complexes and their probable binding sites in penicillin binding protein (PBP2). Moreover, drug-likeness and toxicity of the compounds were also performed to predict the suitability of the complexes as drugs. (C) 2020 Elsevier B.V. All rights reserved.

Ionic liquids as entrainers for terpenes fractionation and other relevant separation problems

This work discusses the potential of two phosphonium-based ionic liquids (ILs), [P-6,P-6,P-6,P-14]Cl and [P-6,P-6,P-6,P-14][(C8H17)(2)PO2], and one methylimidazolium-based IL, [C(4)rnim][OAc], as entrainers in the fractionation of terpene mixtures, in the desulfurization and denitrification of fuel oils, and in the separation of aromatics from aliphatic hydrocarbons. To this aim, the activity coefficients at infinite dilution of 45 solutes were obtained by gas-chromatography in the temperature range (333.15-458.15) K. Selectivities and capacities were calculated showing that [P-6.6.6,P-14]Cl is adequate for the fractionation of (-)-menthone/L-(-)-menthol mixture, being also a suitable option for the deterpenation of citrus essential oil, and the removal of thiophene and pyridine from aliphatic hydrocarbons. To complement the experimental measurements COSMO-RS model was tested, demonstrating good potential to screen separation agents and give insights for several important separation problems, including the removal of contaminants from fuels and the isolation, fractionation and purification of terpenes mixtures.
