POLARIZED PHOTOLUMINESCENCE OF LIQUID-CRYSTALLINE POLYMERS WITH ISOLATED ARYLENEVINYLENE SEGMENTS IN THE MAIN-CHAIN

Anisotropic charge transport, or polarized photo- and electroluminesce nce are possible applications for materials combining the optical prop erties of arylenevinylene polymers with the characteristic orientation al order of the liquid-crystalline state. Thermally stable, soluble ma terials with a broad mesophase, which can be oriented macroscopically using conventional processing techniques and which exhibit highly anis otropic luminescence behavior of use in polarized LEDs are presented.
