Two types of monomers such as 2-(prop-2-enoyl)hydrazine-1-carbothioamide [I] and 5-ethenyl-4H-1,2,4-triazole-3-thiol [II], along with their derivatives such as S-(5-ethenyl-4H-1,2,4-triazol-3-yl) prop-2-enethioate [III] and polymers [P1], [P2], and [P3], have been examined in this research work. DSC and POM are used for studying the phase transitions and liquid crystallinity nature of all monomers and polymers under study. Purely nematic phase is observed in monomer [I], while dimorphism is displayed by monomers [II] and [III] with respect to smectic A (SmA) and nematic phases. Nematic phases are exhibited in polymers [P1] and [P2], while polymer [P3] shows SmA and nematic.
