Esterlinkers enhance self-association: New fluorescent thienopyrrole-fused thiadiazoles (TPTs) with either ester or ether bridging groups were synthesized. The subtle replacement of etherlinkers by esterlinkers leads to a distinct increase (ca. 3–4 fold) in the association constant and the enthalpic contribution (ca. 3 kcal mol−1). The TPTs having esterlinkers produced 1D self-assembled clusters

A new disc-like triphenylamine containing mesogenic compound has been synthesized by the implementation of the Heck and ring-closing metathesis-based reactions in good yield. The designed and synthesized compound showed rectangular columnar mesophase and this is the first report of liquid crystalline phase of the triphenylamine-based compound with an olefinic linkage. The disc-shaped compound exhibited excellent fluorescence properties. (C) 2009 Elsevier Ltd. All rights reserved.
