The various models of representation of molecular structure from 2D up to 4D are used for studying of connection "structure-mesomorphic properties". The transition effect from modification B1 to modification B2 which characterized by antiferroelectric properties at electric field is found out in series of 2,7-dihydroxynaphtalene derivatives. Methods of 5,11,17 23-tret-butyl-25,27-dihydroxy- and 25,27-disubstituted kalix [4] arene-(aza)-craun esters preparation were made up. Influence of the kalixarene macrocycle size on selective complexing with alkline ion is studied. Product Description popup.authors popup.nrat_date 2020-04-02 Close
