New Insight into Charge-Transfer Enhancement for SERS in Cosputtering (Ag)(x)(ZnS)(y) System: The Carrier Density Effect

Cosputtering technology was utilized to combine Ag with ZnS at different doping contents into a new material, which was referred to as the (Ag)(x)(ZnS)(y) (x = 10 W, y = 20, 40, 60, 80, 100 W) system. The carrier density is characterized through the Hall effect, and the change in the bandgap distribution due to the change in carrier density is calculated by ultraviolet photoelectron spectroscopy (UPS). By increasing the sputtering power of the ZnS in the (Ag)(x)(ZnS)(y) system, the carrier density and the conduction band (CB)/valence band (VB) were decreased. Interestingly, we found a liner relationship between the surface-enhanced Raman scattering (SERS) intensity ratio of b(2) to a(1) bands and the carrier density, which intuitively expresses that I-b2/I-a1 increases as the carrier density decreases. The development of the carrier density regulation of SERS materials can be used to monitor the possible CT enhancement for SERS.

Investigation of X-ray crystal structure and in vitro cytotoxicity of two Ga(III) complexes containing pyridine dicarboxylic acid derivatives and 2-aminobenzimidazole

Two new coordination complexes were synthesized using the reaction of two organic salts with gallium(III) nitrate octahydrate. The salts were prepared and used as ligand from the reaction of 2-aminobenzimidazole with pyridine-2,6-dicarboxylic acid and 4-hydroxypyridine-2,6-dicarboxylic acid, respectively. All compounds were identified by spectroscopic methods and their crystal structures determined by single crystal X-ray diffraction. The investigations showed that the two complexes were isostructural. Moreover, thermal analysis was carried out to study the decomposition steps of the complexes. The inhibition properties of the compounds were studied in vitro using oxaliplatin as a standard against five cell lines including a human breast cancer, a prostate cancer, a human liver hepatocellular carcinoma, a colorectal carcinoma and a human foreskin fibroblast. The anti-proliferative activity of the complexes was found to be similar in the majority of cell lines except for the prostate cancer cells. The most remarkable cytotoxicity effect of both complexes appeared on the human breast cancer cells. Determination of mitochondrial membrane potential and reactive oxygen species in this cell line suggested that apoptosis may be the main pathway for the death of the cells. (C) 2020 Elsevier B.V.

In Situ Bottom-up Synthesis of Porphyrin-Based Covalent Organic Frameworks

Synthesis and processing of two- or three-dimensional covalent organic frameworks (COFs) have been limited by solvent intractability and sluggish condensation kinetics. Here, we report on the electrochemical deposition of poly(5,10,15,20-tetrakis (4-aminophenyl)porphyrin)-covalent organic frameworks (POR-COFs) via formation of phenazine linkages. By adjusting the synthetic parameters, we demonstrate the rapid and bottom-up synthesis of COF dendrites. Both experiment and density functional theory underline the prominent role of pyridine, not only as a polymerization promoter but as a stabilizing sublattice, cocrystallizing with the framework. The crucial role of pyridine in dictating the structural properties of such a cocrystal (Py-POR-COF) is discussed. Also, a structure-to-function relationship for this class of materials, governing their electrocatalytic activity for the oxygen reduction reaction in alkaline media, is reported.

Reductive Coupling of (Fluoro)pyridines by Linear 3d-Metal(I) Silylamides of Cr-Co: A Tale of C-C Bond Formation, C-F Bond Cleavage and a Pyridyl Radical Anion

Herein, we disclose the facile reduction of pyridine (and its derivatives) by linear 3d-metal(I) silylamides (M=Cr-Co). This reaction resulted in intermolecular C-C coupling to give dinuclear metal(II) complexes bearing a bridging 4,4 ‘-dihydrobipyridyl ligand. For iron, we demonstrated that the C-C coupling is reversible in solution, either directly or by reaction with substrates, via a presumed monomeric metal(II) complex bearing a pyridyl radical anion. In the course of this investigation, we also observed that the dinuclear metal(II) complex incorporating iron facilitated the isomerisation of 1,4-cyclohexadiene to 1,3-cyclohexadiene as well as equimolar amounts of benzene and cyclohexene. Furthermore, we synthesised and structurally characterised a non-3d-metal-bound pyridyl radical anion. The reactions of the silylamides with perfluoropyridine led to C-F bond cleavage with the formation of metal(II) fluoride complexes of manganese, iron and cobalt along with the homocoupling or reductive degradation of the substrate. In the case of cobalt, the use of lesser fluorinated pyridines led to C-F bond cleavage but no homocoupling. Overall, in this paper we provide insights into the multifaceted behaviour of simple (fluoro)pyridines in the presence of moderately to highly reducing metal complexes.

Effect of alkyl substituent on molecular configuration in a Cu(II) complex: Synthesis of Cu and CuO nanoparticles using a single, solid-source precursor

A new hydrazone-type ligand, methyl 4-(pyridine-4yl-methylene) hydrazinecarboxylate (C8H9N3O2; 4-pymc) and its Cu(II) complex [Cu(4-pymc)(2)(CH3COO)(2)(H2O)] (1) were prepared and characterized. The structure of 1 comprises monomers in which Cu is five-coordinated with a distorted square pyramidal structure. Oxygen atoms of two monodentate acetate anions and a pair of nitrogen atoms from pyridine rings form the basal plane. The apical position is filled by a water molecule. Further, the TEM images demonstrated successful preparation of both Cu (similar to 35 nm) and CuO (similar to 95 nm) nanoparticles (NPs) using the single source as-prepared Cu(II) complex via a thermal decomposition approach simply by changing the atmospheric conditions (i.e., vacuum and air atmospheres) under which the Cu(II) complex was calcined for 1 h at 400 degrees C. Furthermore, the TG-DTA studies indicate that 1 underwent endofollowed by exo-thermic decomposition to form CuO as the end residue in an air atmosphere. The production of Cu and CuO NPs was corroborated by powder x-ray diffraction (PXRD) analysis. The sharp and high intensity PXRD peaks of the calcined samples corroborated that the formed NPs had no impurity and high crystallinity. Furthermore, both ligand and Cu(II) complex showed photoluminescence properties. Also, we demonstrated that the prepared 1 can act as a single, solid-source precursor to form both Cu and CuO NPs.

Finely Tuned alpha,alpha ‘-Bis(arylimino)-2,3:5,6-bis(pentamethylene)pyridine-Based Practical Iron Precatalysts for Targeting Highly Linear and Narrow Dispersive Polyethylene Waxes with Vinyl Ends

One-pot template construction of alpha,alpha’-bis(arylimino)-2,3:5,6-bis(pentamethylene)pyridyl iron chlorides achieved by reacting alpha,alpha’-dioxo-2,3:5,6-bis(pentamethylene)pyridine and the corresponding anilines along with the respective iron chloride in acetic acid provided yields of 26-76%. All these complexes were characterized by FT-IR, elemental analysis, H-1 NMR, and X-ray diffraction analysis. Distorted-square-pyramidal geometries are observed in the molecular structures of Fe1 and Fe6, respectively. When MAO or MMAO is used as a cocatalyst, Fe1-Fe5 display a high activity of 10(7) g with highly linear, low-molecular-weight, and narrow-polydispersity polyethylenes (PEs) being obtained by ethylene polymerization. The catalytic activity of Fe1 reached a maximum activity ((3.81-3.93) x 10(7) g of PE (mol of Fe)(-1) h(-1)) by using the cocatalyst MAO or MMAO at Al/Fe ratio of 5000. All of the synthesized iron precatalysts Fe1-Fe8 containing sterically ortho benzhydryl and aryl (2,4,6-substituents of the aryl ring) groups delivered catalytic activities in the order Fe1 (Me)(2)CH(Ph)(2) > Fe5 Cl(CHPh2)(2) > Fe2 Me(CHPh2)(2) > Fe3 Et(CHPh2)(2) > Fe4 Pr-i(CHPh2)(2) >> Fe6 (CHPh2PrCHPh2)-Pr-i Fe7 (CHPh2BuCHPh2)-Bu-t approximate to Fe8 CHPh2 FCHPh2. Of note, this developed catalytic system was also used in scale-up ethylene polymerization with a high activity of up to 48.10 x 10(6) g of PE mol(-1).

Porous POM/PLLA membranes decorated with gold nanoparticles as flexible and efficient plasmonic substrates for surface-enhanced Raman scattering

In this work, we have developed a flexible and efficient Surface-enhanced Raman scattering (SERS) substrate by a facile way of fabricating gold nanoparticles (NPs) decorated Poly(oxymethylene)/poly(L-lactic acid) (POM/PLLA) membranes. Firstly, POM/PLLA membranes were aminolyzed by 1,6-hexanediamine to render the membranes with amino groups and porous structure simultaneously. The membranes were then immersed in tetrachloroauric acid (H4AuCl4) solution, where the AuCl4- anions were able to complex with the free amine groups of POM/PLLA, followed by in situ reduction by sodium borohydride to immobilize Au NPs on POM/PLLA membranes. The POM/PLLA/Au membranes exhibited high SERS sensitivity as well as good Raman signal reproductivity for rhodamine 6G (R6G). The minimum detection concentration was 10(-14) M and the enhancement factor was calculated to be 1.54 x 10(9).
