In this work, hexa-substituted cyclotriphosphazenes bearing 1,3,4-oxadiazole groups as fluorophores were employed in the formation of thin films. The compounds well films exhibited photoluminescence with emission UV-blue region. Fluorescence quantum yields range between 0.04 and 0.10. bandgap was 4 eV showing properties wide semiconductors. morphological characterization by SEM AFM showed homog...

The structure of the oxadiazole skeleton is a biologically and biochemically active nucleus that has multiple number biological activities. five-membered aromatic ring been used in numerous studies molecules synthesised laboratories. principle Oxadiazole with pair Pyridine-type nitrogen atoms confirmed to be valuable for analogues having efficacious protein interactions large enzyme proteins re...

The aim of the present work was to synthesise coumarinyl heterocycles and to elucidate the potential role of these compounds as antioxidants and cytotoxic agents against Dalton's lymphoma ascites tumour cells (DLA) and Ehrlich ascites carcinoma cells (EAC). The synthesis of coumarin derivatives containing pyrazole, pyrazolone, thiazolidin-4-one, 5-carboxymethyl-4-thiazolidinone and 3-acetyl-1,3...
