Original language description
New series of chiral aliphatic and aromatic esters of 7-decyl[1]benzothieno[3,2-b][1]benzothiophene-2-carboxylic acid were synthesised and their mesomorphic behaviour was studied. While the chiral aliphatic esters exhibited only the SmA phase, the antiferroelectric SmCA* phase was found for esters with chiral 4-hydroxybenzoates, in one homologue accompanied also by a ferroelectric SmC* phase. Introduction of lateral substituents in the 3 position of the 4-hydroxybenzoic acids (methoxy, fluoro, chloro, and bromo) led to reduction of polymorphism and only the SmA phase remained.
