Synthesis and characterization of new poly(p-phenylenevinylene) derivative containing 5,5′-diphenyl-2,2′-p-(2,5-bis-hexyloxyphenylene)-bis-1,3,4-oxadiazole and distyrylbenzene moieties

A PPV-based conjugated copolymer DIOXA-PPV containing electron-affinitive bis-1,3,4-oxadiazole and hole-transporting distyrylbenzene derivative was synthesized via Horner–Wadsworth–Emmons reaction. The HOMO, LUMO energy levels and band gap of DIOXA-PPV ar
