Abstract

Light-emitting liquid crystals incorporating two photopolymerizable end groups have been synthesized for implementation in multilayer organic electroluminescent devices. Series of diene as well as diallylamine and methacrylate moieties are used as the photoreactive groups attached via spacers to both ends of a fluorene-based chromophore. Nematic glasses are formed upon cooling from the liquid crystalline phase. Ultraviolet radiation at ...
