A novel family of phasmidic liquid crystals incorporating an oligo(p-phenylenevinylene) core was produced. These compounds exhibit blue luminescence in both solution and the solid state. The emission profiles are influenced by the degree of organization in the solid state. The snthesis and liquid-crystalline behavior of these compounds will be discussed. Their photophysical properties, as studied by c.w. photoluminescence excitation, emission spectroscopy, and site selective spectroscopy, as well as their optoelectronic properties will be presented.

Hexacatenar LCs containing a shorter 1, 4-distyrylbenzene core have been previously synthesized. Emission behavior from these smectic hexacatenar systems was not documented. See: H. Meier, E. Prass, G. Zerban, and F. Kosteyn, Z. Naturforsch. 7, p. 923 (1995).
