Abstract:

Polycatenar liquid crystals have been known since 1985. They consist of a long rod-like rigid core ending in two half-disc moieties. The molecular architecture of such hybrid mesogens, situated between rod-like and disc-like mesogenic compounds, allows a rich polymesomorphism. On the other hand, efficient light-emitting diode (LED) materials derived from heterocyclic benzobisazoles have been studied. An efficient _- stacking and strong intermolecular interaction were attributed to some novel physicochemical and mechanical properties observed in such materials. In this work, new mesogenic polycatenar have been prepared, with the incorporation of benzo bisthiazole.
