| 英文摘要 | Two pairs of calamitic liquid crystalline molecules, (1)-2-[4'-(S)-sec-butoxyphenyl]- 5-(4'-hexoxyphenyl) toluene ((1)-S-1) and (1)-2-(4'-hexoxyphenyl)-5-[4'-(S)-sec-butoxyphenyl] toluene ((1)-S-2), (2)-2-[4'-(R)-sec-butoxyphenyl]-5-(4'-hexoxyphenyl) toluene ((2)-R-1) and (2)-2-(4'-hexoxyphenyl)-5-[4'-(R)-sec-butoxyphenyl] toluene ((2)-R-2), have been designed and synthesized. Each of the molecules consists of a p-terphenyl core substituted with a methyl group on the middle ring, a chiral sec-butoxy tail, and an achiral n-hexoxy tail. The geometrical difference between (1)-S-1 ((2)-R-1) and (1)-S-2 ((2)-R-2) lies only in the location of the methyl group on the effective mesogenic core. Yet, such a small change in the structure gives rise to remarkable differences in mesogenic properties and handedness. Both (1)-S-1 and (2)R- 1 have an enantiotropic cholesteric phase (N*) and a monotropic twist grain boundary C* phase (TGBC*), whereas (1)-S-2 and (2)-R-2 exhibit only a monotropic N* phase. Moreover, (1)-S-1 ((2)-R-1) and (1)-S-2 ((2)-R-2) have opposite handedness in the N* phase, and (1)S- 1 and (2)-R-1 even have a helical inversion from N* to TGBC* phase through a non-helical chiral mesophase.
