Emissive Anisotropic Polymeric Materials derived from Liquid Crystalline Fluorenes

Abstract

Abstract The synthesis and characterization of photoluminescent crosslinking agents containing a fluorene core are described. They exhibit an efficient fluorescence and have a promesogenic molecular shape that depending on the substitution results in the development of thermotropic mesophases. A difunctionalized fluorene derivative has been incorporated into a liquid crystal host in order to produce polarized light emitting films. These films have been prepared by the in-situ photopolymerization technique. Keywords: FluorenesLiquid CrystalsPhotoluminescencePhotopolymerizationPolarized Emission
