We report an organic emitter containing a β-triketone electron acceptor core and phenoxazine as the donors (TPXZBM) for solution-processed light-emitting diodes (OLEDs). The resulting molecule is very unusual because it shows both thermally activated delayed fluorescence intramolecular proton transfer. compare its performance with previously reported diketone analogue PXZPDO. Solution-processed...

Bis-thiosemicarbazones derived from the ?-diketone benzoylacetone (H3banR, R=Me, Et, Ph) are potentially tetradentate N2S2 ligands whose coordination chemistry with copper is reported. In absence of oxygen and in presence base they form anionic CuII complexes fully deprotonated [CuII(banR)]–. Upon exposure to atmospheric undergo a complex series reactions leading two types products; one ligand ...

Aldose reductase (ALR2) inhibition is the most legitimate approach for the management of diabetic complications. The limited triumph in the drug development against ALR2 is mainly because of its close structural similarity with the other members of aldo-keto reductase (AKR) superfamily viz. ALR1, AKR1B10; and lipophilicity problem i.e. poor diffusion of synthetic aldose reductase inhibitors (AR...

Aldolase antibodies that operate via an enamine mechanism were developed by in vitro selection. Antibody Fab phage display libraries were created where the catalytic active site residues of aldolase antibodies 38C2 and 33F12 were combined with a naive human antibody V gene repertoire. Selection from these libraries with 1,3-diketones covalently trapped the amino groups of reactive lysine residu...

A series of enolic Schiff base aluminum(III) complexes LAlR (where L=NNOO-tetradentate enolic Schiff base ligand) containing ligands that differ in their steric and electronic properties were synthesized. Their single crystals showed that these complexes are five-coordinated around the aluminum center. Their coordination geometries are between square pyramidal and trigonal bipyramidal. Their ca...

Natural pigments derived from microorganisms have many advantages and are widely studied in the food industry. A filamentous fungus, DBFL05, was identified as Aspergillus ustus, which produces a bright abundant brown pigment. This extracellular, water-soluble pigment is highly polar slightly soluble alcohol but insoluble other organic solvents. The stable under sunlight, at pH 2–10, below 100°C...
