Discogene Amido- und Azido-Derivate von Desoxy-scyllo-inositol

Abstract

Three discotic liquid crystalline derivatives (2, 3, and 5) of 1-amino-1-deoxy-scyllo-inositol are described. The polar molecules have a non-centrosymmetric structure and represent the first thermotropic discogens with lateral functions attached to the «core» through nitrogen. Moreover, 5 is the first mesogene at all containing an azido function. As has been found by microscopy these novel compounds exhibit mesophases of probably equal type (D_ho) over very wide ranges of temperature, e.g. ΔT ≈ 229 °C for 3 which is about 100 °C wider than that one of its oxygen analogue, scyllo-inositol hexakis-hexanoate.
