Abstract
Official abstract text for this publication.
To provide a liquid crystal compound having a large negative value of dielectric anisotropy (Δ∈). A compound is represented by formula (1): wherein, in formula (1), one of Y 1 and Y 2 is fluorine, and the other is CF 2 H or CF 3 ; G is a ring represented by formula (pr-1) or formula (pr-2): wherein A 1 to A 3 are independently 1,4-cyclohexylene or 1,4-phenylene; R a and R b are independently hydrogen, alkyl having 1 to 20 carbons, or the like; Z 0 , and Z 1 to Z 3 are independently a single bond, —(CH 2 ) 2 —, —CH═CH—, —CF 2 O—, —OCF 2 —, —CH 2 O—, —OCH 2 —, —COO— or —OCO—; j, m and n are an integer from 0 to 2, and a sum of j, m and n is 0, 1 or 2, however, when m is 0, Y 1 is CF 2 H or CF 3 , Y 2 is fluorine, and Z 0 is a single bond, G is a ring represented by formula (pr-1).
