Fluorinated indenes and 1,7-dihydroindacenes of negative dielectric anisotropy

摘要

Fluorinated indenes and 1,7-dihydroindacenes of the general formulae (I) and (II) of negative dielectric anisotropy (Deltaepsilon<0) in which T, A, R, L, X, Y, U, W, Z, n, m, p and q are as defined herein are suitable for use in liquid crystal display elements.
