标题:Synthesis And Mesomorphic Properties Of Some Liquid Crystals With 2,3,5,6-Tetrafluorophenylene Unit
摘要:Nine Fluorosubstituted Liquid Crystals Have Been Synthesized And Their Mesomorphic Properties Have Been Studied By Texture Observation In A Polarizing Microscope And Confirmed By Dsc. They Show Enantiotropic Smectic A And Nematic Phases. The Effect Of Terminal And Lateral Fluorosubstitution Is Also Discussed.
