Design and Synthesis of New Liquid Crystal Materials with Fluoro-Substituted Fused Ring Structure for Active Matrix LCD (1)

Abstract

Novel 1-fluoro- and 1,2-difluoronaphthalene derivatives were designed for active matrix LCD and were prepared through the regioselective fluorination of 6-substituted 2-naphthols. These compounds exhibited high nematic-isotropic transition temperatures with very large dielectric anisotropy and large birefringence.
