PBb08 非対称型ダイマー液晶の合成とその相転移挙動

抄録

A new series of non-symmetrical dimeric compounds including two distinct mesogenic groups, 4-(4'-benzyloxy)biphenyl cholesteryl alkanedioate (abbreviated hereafter to BBChA-n, where n is the number of carbon atoms in the methylene chain unit), was prepared in our laboratory. Thermal properties of these compounds have been studied by differential scanning calorimeter and polarizing microscope. In addition, two symmetrical dimeric compounds, namely dicholesteryl decanedioate (diChA-8) and di[4-(4'-benzyloxy)biphenyl] decanedioate (diBBA-8) were synthesized and their phase transition behavior was studied by the same methods in order to compare with those of BBChA-n.
