Abstract
Copolymers containing quaterphenyl and sexiphenyl units in which the solubility was introduced by spacer groups were prepared and investigated. Photoluminescence of the compounds appears in the blue region of the visible light. Blue light emitting electroluminescent devices based on the blends of the quaterphenyl copolymer and poly(N‐vinylcarbazole) with indium‐tin oxide(ITO) and aluminium as hole‐ and electron‐injecting electrodes, respectively, were fabricated. Further, the quaterphenyl copolymer was found to be nematic between 236 and 244°C.Keywords
