Title:
光重合性オキセタン誘導体およびそれらを含む液晶組成物
Document Type and Number:
Japanese Patent JP4586520
Kind Code:
B2
Abstract:
Provided are a liquid-crystal compound and a liquid-crystal composition containing the compound, of which the advantages are that they show nematic hybrid orientation on a rubbed TAC substrate, they are polymerizable in open air and they readily give a polymer having a high degree of polymerization even when exposed to a relatively small total quantity of light. The films formed by photopolymerizing them keep nematic hybrid orientation. The compound is represented by formula (1): wherein R1 is a hydrogen or an alkyl; R2 is a hydrogen, -OCF3, etc.; A1 is a 1,4-phenylene, etc.; A2 and A3 are independently a 1,4-cyclohexylene, a 1,4-phenylene, etc.; X1 is a single bond, -O-, etc.; X2 and X3 are independently a single bond, -COO-, -C≡C-, -CONH-, etc.; m is an integer of from 0 to 20; and n is 1 or 0.
