Liquid crystalline properties of some derivatives with a long lateral alkoxyl group
This paper describes the liquid crystalline properties of 4-(4-alkoxy-phenoxycarbonyl)phenyl 4-bromo-3-alkoxy-((2) under bar),4-cyano-3-alkoxybenzoates((3) under bar), and 2-methyl-3-alkoxybenzoates((4) under bar). (2) under bar and (3) under bar are essentially smectogenic, while (4) under bar are nematogenic. The difference in the mesomorphic properties is discussed in terms of their molecular geometrical characteristics estimated by a semi-empirical molecular orbital calculation.
