Silanol compounds containing mesogenic groups, mesogenic groups containing polymerizable monomers and polymers containing mesogenic groups.

摘要

A silanol compound having a mesogenic group, of the following formula (III): CHEM wherein each of R5 and R6, which may be the same or different, is an alkyl group or a phenyl group, X is a single bond, an oxygen atom, or a group of the formula -COO- or -OCO-, Q is a mesogenic group, and p is an integer of from 2 to 20, and a process for its production. Also disclosed are a polymerizable monomer of the following formula (I) and a polymer having repeating units of the following formula (II). CHEM wherein R is a hydrogen atom, a halogen atom, an alkyl group or a phenyl group, each of R1 to R6, which may be the same or different, is an alkyl group or a phenyl group, m is an integer of from 2 to 20, n is an integer of from 0 to 50, and X, Q and p are as defined above.
