  Liquid crystal materials having a fluoro-substituted tetralhydro-naphthalene structure were designed for active matrix LCD. 6-Aryl-5-fluoro-1,2,3,4-tetrahydronaphthalenes and 5,6-difluro-1,2,3,4-tetrahydronaphthalenes were prepared by regioselective fluorination and hydrogenation of 2-naphthols. 6-Aryl-5,7-difluoro-1,2,3,4-tetrahydronaphthalenes were synthesized from 5,7-difluoro-1,2,3,4-tetrahydronaphthalene-2-one. The liquid crystal mixture containing these compounds with very good co-solubility exhibits a wide nematic temperature range with low melting point and very large value of dielectric anisotropy. From these results these compounds are useful for design. of new liquid crystal mixtures for TFT-displays.
