Реферат: Schiff bases of 2-substituted 5-aminopyrimidines were synthesized, and their liquid-crystal and dielectric properties were investigated. It is shown that narrow ranges of the existence of meso phases and a greater (as compared with benzyl-ideneanilines) tendency for the development of a smectic state are characteristic for 2-alkoxy-, 2-alkyl-, and 2-cyano-5-arylideneaminopyrimides. The introduction of an aryl substituent into the 2 position of the pyrimidine ring gives rise to a pronounced increase in the thermostability of the meso phase and significantly increases the range of its existence. The use of groups with higher dipole moments as terminal groups leads to the production of compounds with high positive dielectric anisotropies. © 1983 Plenum Publishing Corporation.
