A blue light-emitting statistical poly(p-phenylenevinylene) (PPV) copolymer with hole-transporting carbazole and electron-transporting oxadiazole pendant groups attached to the kinked in-terphenyl unit was prepared by Heck coupling between 1,4-divinylbenzene and dibromides. The latter were synthesized through pyrylium salts. The polymer had optical band gap of 2.89 eV and emission maximum at 446 nm in THF solution and 434 nm in thin film. It showed a pure blue emission with no aggregates or excimers formed even in solid state because of the long and bulky pendant groups.
