Abstract

The synthesis of a novel family of liquid crystals, cyclic compounds without chain ends, raises a series of fundamental questions, since many technological applications of conventional rod-like low molecular weight liquid crystals rely on teh chain ends for alignment. The figure shown the conformation of the cyclic tetramer in the nematic phase.
