Abstract

The synthesis and liquid-crystalline properties of 4-(heptyloxy)-N-(aryl)benzaldimin-2-ols have been described. The compounds obtained have smectic and nematic mesomorphism. Alternation of the bleaching temperatures (Tbl) with variation of the length of the alkyl radical in the N-aryl fragment has been noted. The dependence of Tbl on the contribution of the substituent to the polarizability of the molecule γ2 is expressed by the equation Tbl=9.7+1.7γ2.
