Effect of Sequence Distribution of Oxadiazole Moieties on Luminescence in a Poly(Phenylene-Vinylene) Derivative

  • Subramanian Vaidyanathan (a1) and Mary E. Galvin (a1)


In order to realize the vast potential offered by semiconducting polymers in emissive display technologies, it is important to understand the structure-property relationships that govern their performance. This paper will focus on one such relationship in the most widely studied class of polymers viz. poly(phenylene-vinylene) (PPV) derivatives. We have synthesized oxadiazole containing PPV copolymers varying the composition and sequence distribution of the oxadiazole moiety in the chain. We find that a statistically random copolymer performs 50% better in EL efficiency than the corresponding alternating copolymer with the same chemical composition, and 3 times better than the homopolymer without any oxadiazole moieties.
