Synthesis and characterization of thiophene and fluorene based donor-acceptor conjugated polymer containing 1,3,4-oxadiazole units for light-emitting diodes

A new donor-acceptor (D-A) conjugated polymer (PDTOF) is synthesized by using Wittig reaction. Polymer light-emitting diode devices fabricated using PDTOF as the emissive layer emitted green light.
