The binding behavior of nanoaggregates of pentacenequinone derivative 1 having thiophene groups has been investigated toward various cations (Fe(3+), Fe(2+), Pd(2+), Mg(2+), Cd(2+), Hg(2+), Ni(2+), Zn(2+), Cu(2+), Pb(2+), Co(2+), K(+), Na(+) and Li(+)) using UV-vis and fluorescence spectroscopy. Among the various cati…
The synthesis of three nitro-functionalized Zn(II)-paddlewheel based metal–organic frameworks (MOFs) and a Zn(II)-based 2D coordination polymer are reported. While 2-nitro-[1,1′-biphenyl]-4,4′-dicarboxylic acid (bpdc-NO2) is readily incorporated into structure of extended DMOF (DMOF = 1,4-diazabicyclo[2.2.2]octane MOF…
The first luminescent Bi-Cd-organic framework, Bi2Cd(2,6-pdc)4(H2O)2·H2O (2,6-H2pdc = pyridine-2,6-dicarboxylate), has been synthesized by using bismuth (Bi) oxides and cadmium (Cd) salts as metal sources under hydrothermal conditions. Tunable and white light luminescence was obtained through the doping of different L…
4,7-Bis(3,3′/4,4′-hexylthiophene-2-yl)benzo[c][2,1,3]thiadiazoles (HT–BT–HT) were used as building blocks to construct a series of low bandgap π-conjugated copolymers for photovoltaic applications. The desired copolymers were obtained by incorporating the HT–BT–HT comonomers together with donor or acceptor units, such…
A new versatile mediator for conducting “living” radical polymerization was developed based on diselenocarbonyl compounds. After the optimization of substitution groups, a “universal” diselenocarbonyl compound (O4) was developed and successfully applied to the controlled polymerization of both conjugated and unconjuga…
Highly efficient and transparent multicomponent catalysts for Dye Solar Cells (DSCs) were obtained by \nsimultaneous electrodeposition of platinum and cobalt-sulfide (Pt:CoS) on conducting glass substrates from \na mixture solution of both precursors. At equal charge transfer resistances (RCT), the superior tr…
High-purity samples of potassium trifluoroargentate(II), KAgF3, have been obtained via a novel synthetic pathway. This compound is found to exhibit an order-disorder phase transition around 230 K. Susceptibility measurements indicate that KAgF3 exhibits strong antiferromagnetic (AFM) coupling reminiscent of that found…
The synthesis of some transition metal SrIr1−xMxO3 type oxides is described. These have an orthorhombic perovskite type-structure and are only found when the formal oxidation state of the Ir is approximately equal to +4.5 and for M = Fe, Co, Ni and Zn. Occupancy of the TM eg type orbitals appears to contribute to the…
Introduction. PriMatrix (TEI Biosciences Inc., Boston, MA, USA) is a novel acellular collagen matrix derived from fetal bovine dermis that is designed for use in partial- and full-thickness wounds. This study analyzes the cellular response to PriMatrix in vivo, as well as the ability of this matrix to facilitate norma…
A novel application of SBA-15 functionalized sulfonic acid containing a confined ionic liquid has been introduced to convert various carbonyl compounds to their corresponding dithioacetals and dithioketals at room temperature and under solvent-free conditions. It was found that coating SBA-15-Pr-SO3H with the hydropho…
Based on the mechanism of hydrolytic cleavage of Schiff bases, a 1-aminopyrene based fluorescent chemodosimeter, 3, is reported for the selective detection of Nb(5+) ions in solution. Among the 21 metal ions tested, the chemodosimeter shows a selective fluorogenic 'turn-on' response toward Nb(5+) ions in mixed aqueous…
Eight uranyl–3d block metal ion heterometallic carboxylate complexes including additional 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen) ligands were obtained, mainly under hydrothermal conditions, and their crystal structures were determined. The carboxylate ligands were chosen so as to provide a large range of…
The integration of color filters with microfluidics has attracted substantial attention in recent years, for on-chip absorption, fluorescence, or Raman analysis. We describe such tunable filters based on the micro-flow of liquid crystals. The filter operation is based on the wavelength-dependent liquid crystal birefri…
Poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate-co-styrenesulfonate) was prepared and utilized as a Li+ host material for a cathode in a Li-ion battery. The polymer allowed high density incorporation of the Li+ ion per repeating unit at a positive redox potential near 0.6 V vs. Ag/AgCl. Redox equilibrium invo…
A new series of highly efficient phosphorescent Ir(III) complexes, which have potential applications in solution processable phosphorescent organic light-emitting diodes (PhOLEDs), were synthesized and their photophysical, electrochemical, and electroluminescent (EL) properties were investigated. The Ir(III) complexes…
A mesoporous titanate-based Na+-exchanger with high surface area and tunable pore size has been successfully synthesized by using NaOH-etched silica mesoporous microspheres as templates. Templating against porous silica microspheres followed by etching the templates with base produces amorphous sodium titanate spheres…
Hydrothermal reaction of zinc nitrate, a four-carbon chain dicarboxylic acid, and one of three isomeric dipyridylamide coligands has afforded a family of six new coordination polymers, which have been structurally characterized by single-crystal X-ray diffraction. The binding modes and conformations of the dicarboxyla…
Two novel Co-based metal-organic frameworks (MOFs) were synthesised and characterised using an asymmetrically binding ligand, 4-(4'-carboxyphenyl)-1,2,4 triazole (Hcpt). The isolated [Co3(II)(μ3-O)(OH)(cpt)3(H2O)2]n·xH2O·yDMF, Co-MOF1, exhibits a rhombohedral crystal structure (space group, P63/mc), with a trinuclear…
