Abstract
The polymerizable compound of the present invention is represented by general formula (1) below and can provide a composition that is polymerizable near ambient temperature and exists in a liquid crystal phase at low temperatures. The composition and a (co)polymer of the polymerizable compound of the present invention are liquid crystal substances useful as optically anisotropic materials. (In the formula, each of rings Ato Arepresents a benzene ring, cyclohexane ring, etc.; each of X to Z represents a Calkyl or alkoxy group, Calkenyl group, halogen atom, cyano group, or CH═CR—COO—; each of Rto Rrepresents a hydrogen atom, methyl group, or halogen atom; each of Lto Lrepresents —CHCHCOO—, —COO—, —OCO—, —CHCH—, —O(CH)— (herein, f=1-8), etc.; n represents 0 or 1; and a to c represent such numbers that the polymerizable compound has at least one or more of any of X, Y, and Z).
