Heterocyclic benzothiazole-based liquid crystals: synthesis and mesomorphic properties
Sie-Tiong Ha,Teck Ming Koh,Hong-Cheu Lin,Guan-Yeow Yeap,Yip Foo Win,Siew Teng Ong,Yasodha Sivasothy,Lay Khoon Ong +7 more
TL;DR: In this article, two homologous series of 2-(4-alkanoyloxybenzylidenamino)benzothiazoles and 2-(2-hydroxy-4alkaneyloxy-4-hexadecanoloxybenziels) were synthesized and characterised, where the latter comprised a lateral hydroxyl group, unlike the former.

Heterocyclic pyridine-based liquid crystals: synthesis and mesomorphic properties
TL;DR: A series of new calamitic liquid crystals, 4-{[pyridin-4-yl)methylidene]amino}phenyl 4-alkoxybenzoates comprising a heterocyclic (pyridine) and two phenyl rings core system, terminal alkoxy chain, was introduced in this article.

Sie-Tiong Ha,Lay Khoon Ong,Siew Teng Ong,Guan-Yeow Yeap,Joanna Pik Wan Wong,Teck Ming Koh,Hong-Cheu Lin +6 more
TL;DR: In this article, a series of Schiff base esters, 4-(dimethylamino)benzylidene-4′-alkanoyloxyanilines containing even number of carbons at the end group of the molecules (C n −1 H 2 n − 1 COO, n ǫ = 6, 8, 10, 12, 14, 16, 18) were synthesized.
