We have synthesized novel photoluminescent aromatic conjugated polymers with liquid crystallinities by introducing liquid crystalline (LC) groups into side chains of poly-jvra-biphenylene (PBP) and poly-para-phenylenevinylene (PPV). The LC group is composed of cyanobiphenyl (CB) or phenylcyclohexyl (PCH) moiety as a mesogenic core. Both types of polymers were fusible and soluble in organic solvents. They exhibited monotropic LC behaviors, i.e., the PBP showed nematic phase in the cooling process, whereas the PPV showed nematic and smectic A phases in the cooling process. Besides, they were fluorescent in the region of 480-540 nm, depending on conjugation length of main chain as well as species of LC side chains. A non-oriented film of the PPV showed electrical conductivities of 10^-5 and 10^-3S/cm before and after iodine doping, respectively. Electrical and optical anisotropies of the present polymers are discussed from advanced multifunctional materials.
