Liquid Crystal Phase Behavior of Novel Mesogenic Compound with Trifluoromethyl Substitutent

Abstract:

In order to obtain a novel liquid crystal compound with trifluoromethyl substitutent, Sonogashira coupling reaction was used to synthesize the mesogenic compound based on tolane. Firstly, 1-iodo-4-trifluoromethyl-benzene was modified with acetylene groups, and then coupled with iodo amyl biphenyl through Sonogashira reaction to obtain the target compound. Moreover, the liquid crystal phase behaviors including transition temperatures and phase sequences were investigated by DSC and POM.
