Abstract

Alternating copolymer of distyrylenediethylhexyloxyphenylene and phenyltriazine(PPVT) or hydroxyphenyltriazine(PVOT) is synthesized in order to enhance the electron mobility in the light emitting polymers. Photoluminescence(PL) spectrum of PPVT shows excimeric characteristics but PVOT generates excitonic PL emission. A blend of PVOT with polyvinylcarbazole(PVK) enhances the PL intensity of PVOT on photoexcitation of PVK indicating an efficient energy transfer. The excimeric PL emission of PPVT is suppressed on photoexcitation of a blend with PVK at the UV-visible absorption(AB) maximum of PVK, which is an indirect photoexcitation, while the energy transfer from PVK to PPVT is not completed.
