Abstract

Two novel gallic trimer7and tetramer8based on acylhydrazone structures were designed and synthesized in yields 76% and 81%, respectively. Their structures were confirmed by1H NMR, ESI-MS, and elemental analysis. Their mesomorphic properties were investigated by DSC, POM, and XRD analyses. The mesomorphic results suggested that they possessed good room-temperature columnar liquid crystalline property with wide range of mesomorphic temperature. The ranges of mesomorphic temperatures for compounds7and8were as wide as 115°C and 124°C, respectively. [ABSTRACT FROM AUTHOR]
