Polymerizable compound, polymerizable liquid crystal composition containing the same, and optically anisotropic medium made from the composition

摘要

A polymerizable compound represented by formula (I): wherein Q1 and Q2 each independently represent a hydrogen atom or a methyl group; p and q each independently represent an integer of 2 to 18; X1 and X2 each independently represent a single bond, -O-, -COO- or -OCO-; L1 represents -COO- or -OCO-; L2 represents -CH2CH2COO- or -CH2CH2OCO-; and Y1, Y2 and Y3 each independently represent a hydrogen atom, an alkyl group having 1 to 7 carbon atoms, an alkoxy group having 1 to 7 carbon atoms, an alkanoyl group having 2 to 7 carbon atoms, a cyano group or a halogen atom. Also disclosed are a polymerizable liquid crystal composition containing the compound, and an optically anisotropic medium produced from the composition.
