4-[4-正烷氧基-2,3,5,6-四氟苯基)乙炔基]苄氧基苯甲酸正戊酯的合成及相变研究

The Synthesis and Mesomorphic Properties of 4'-n-pentoxy4"-[ (4-n-alkoxy-2, 3, 5, 6-tetrafluorophenyl) ethynyl] benzoates

本文报导了一类新型含全氟苯炔类液晶化合物4-[4-正烷氧基-2,3,5,6-四氟苯基)乙炔基]苄氧基-苯甲酸正戊酯合成及相变性质,并讨论了末端碳链对相变性质的影响。

A novel series of 4'-n-pentoxy 4" [4-n-alkoxy-2, 3,5, 6-tetrafluorophenyl) ethynyl] ben-zoates have been synthesized and the relationship between their mesomorphic properties and length of end chain have also been discussed.
