摘要

PROBLEM TO BE SOLVED: To obtain a new compound bearing liquid crystal disposition over a wide temperature range, having a dianhydrohexit derivative as chiral group, by reaction of a SiH group-bearing organosiloxane or organosilane with a methogen group-bearing compound, etc. ;SOLUTION: This new liquid crystal organosiloxane is expressed by formula I {Hexit is dianhydrohexit group; M¹ is a group of formula II [R¹ is C_nH_m ((n) is 0-20; (m) is 2n, when (n) is ≥2, (m) may be 2n-2), one or more CH₂ not adjacent to each other may be substituted by 0 or dimethylsilyl; A¹ and A² are each 1,4-phenylene, 1,4-cyclohexylene, etc.; X¹ is OCO, CO, etc.; Z¹ is an alkylene, COO, CH=CH, etc.; (a) and (b) are each 0-3; (r) is 0 or 1]; M² is a group of formula III (R² is H, OH, a polymerizable group, etc.; R³, X² and Z² are the same as R¹, X¹ and Z¹, respectively; A³ and A⁴ are each the same as A¹; (c) and (d) are each 0-3; (s) is 0 or 1)}, and useful for optical elements, polarized light color filters, decorative materials, etc.;COPYRIGHT: (C)1997,JPO
