| Abstract: | Abstract This paper describes the liquid the crystalline properties of 4-(4-alkoxy-phenoxycarbonyl)phenyl 4-bromo-3-alkoxy-(2), 4-cyano-3-alkoxybenzoates(3), and 2-methyl-3-alkoxybenzoates(4). 2 and 3 are essentially smectogenic, while 4 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. |
