Poly[2-{5'-(4"-t-butylphenyl)-1',3',4'-oxadiazole}-1,4-phenylenevinylene (BPOD-PPV)] containing 4-t-butylphenyl-1,3,4-oxadiazole pendant was synthesized by Gilch reaction. Me obtained polymer shows a strong absorption centered around 300 nm and broader peak at about 350-520 nm. The efficiency of ITO/PPV/polymer/Al device is greater than by more than 2 orders of magnitude when compared with the ITO/PPV/Al device.
