High transverse dipole moment aryl compounds

摘要

A fluorinated phenyl compound having the general formula Ä1Ü: wherein each of s, v and x=0 or 1, each of t and u=1, 2 or 3, and each of y and z=0, 1 or 2; A, B and C are independently selected from conjugated cyclic moieties including heterorings and fused rings; R1 and R3 may be independently cyano, or (C1-C12)alkyl, (C1-C12)alkoxy, (C1-C11) alkoxycarbonyl or (C1-C11)alkylcarbonyloxy which may be fluoro- and/or cyano-substituted; R2=H or F; R4=H or F; and R5=H or F. Such compounds have high transverse dipole moments and are potentially useful in liquid crystal compositions and in devices including same.
