## Abstract The luminescent copolymer 2βphenylβ5β[3β²β(methacrylamido)phenyl]β1,3,4βoxadiazole and vinylcarbazole (PMAPOβVCZ), combining holeβfacilitating moiety, carbazole ring, and electronβfacilitating moiety, 1,3,4βoxadiazole, as side groups, was synthesized by a radical polymerization of the ol
Starting from some new 2,5-disubstituted-1,3,4-oxadiazole difluorides, synthesized by cyclocondensation of dihydrazides with 4-fluorobenzoic acid, novel poly(arylene ether)s were prepared by halo displacement polymerizations with bisphenol A in the presence of potassium carbonate. Model reactions de
