- Poly(1,1'-biphenyl-4,4'-ylene vinylene-alt-2,5-bis(2-ethylhexyl)-1,4- phenylene vinylene] [poly(BPV-alt-BEHPV)] as a polymeric dopant, was synthesized by Honer-Emmons condensation from corresponding dialdehyde and diphosphonate monomers. Synthesized alternating polymer was used to fabricate single layer (ITO/Host:Dopant/Al) PLEDs with poly(vinyl carbazole) (PVK) as a host. Conjugated poly(BPV-alt-BEHPV) showed green emission from single layer ITO/poly(BPV-alt-BEHPV)/Al device. Emission colors from doped PLEDs were changed by energy transfer from blue originated from PVK to green with increasing the content of poly(BPV-alt-BEHPV).
