摘要
Liquid crystalline conjugated polymers have potential applications as inexpensive, easy to process polarized back lights for liquid crystal displays. Three 'Hairy rod' type conjugated polymers, namely Poly(9,9-dioctylfluorene) [PFO] and two alternating co-polymers with benzothiadiazole and dithiophene moieties in the mainchain, have been investigated. In this paper, we present polarized absorption and photoluminescence for films aligned on rubbed polyimide [PI] alignment layers. We also report electroluminescence measurements for oriented multilayer devices with rubbed hole transporting alignment layers [HTAL]. Sample preparation, device fabrication and characterisation are discussed and a preview of future work is given. (C) 2000 Elsevier Science S.A. All rights reserved.
