Synthesis and characterization of a light-emitting poly(p-phenylenevinylene)-based copolymer containing 1,3,4-oxadiazole functionality
A new class of high brightness and luminance efficiency of poly[2-{4-[5-(3-(3, 7-dimethyloctyloxy)phenyl)-1,3,4-oxadiazole-2-yl]phenyl}-1,4-phenylenevinylene] (C(10)PhOxa-PPV) was synthesized by Gilch polymerization. The weight average molecular weight (Mw) and the polydispersity of C(10)PhOxa-PPV were found to be 2.7 x 10(4) and 2.6, respectively. Double-layer light-emitting device with an ITO/ PEDOT/C(10)PhOxa-PPV/Al was fabricated and characterized. The maximum brightness, and luminance efficiency of C(10)PhOxa-PPV showed values of up to 8.3 cd/A and 4,426 cd/m(2), respectively.
