A series of the Y-shaped liquid crystalline (LC) materials based on central 1,2,4-benzenetricarboxylic core was synthesized with variation of the arm length (two or three para-linked phenyl rings) in the Y-shaped mesogen and their dipole architecture (ether or ester terminal and linked groups). Our results indicate that main relationships between molecular structure and mesomorphic behavior well known for the calamitic LC are valid for the Y-shaped compounds too. Smectic mesophases might be obtained by lengthening the mesogen with an additional aromatic core in the arm or with an alkyl chain at the tail. The substitution of the alkoxy terminal groups on to alkanoyl also leads to the enhanced smectic behavior of the Y-shaped molecules. Taylor & Francis Group, LLC.
