Abstract
An optically active compound having a polymerizable group which is represented by formula (1) or (2).P1-Q1-(A1-Z1)m—X1—(Z1-A1)m-Q1-P2 (1)P1-Q1-(A1-Z1)m—X2 (2)For example, A1 is independently divalent group having ring; Z1 is independently bonding group; m is independently an integer from 1 to 5; Q1 is independently alkylene having 1 to 20 carbons; X1 is a divalent group having chirality; X2 is a monovalent group having chirality, and P1 and P2 are polymerizable groups; and concerns a polymerizable liquid crystal composition, a polymer, an optical device and an article.
