中文摘要	<正>Several series of sugar-containing liquid crystals(LCs)and liquid crystalline polymers(LCPs)were syn- thesized and characterized.The self-assembly of the sugar-containing LCs and LCPs give rise to a variety of specific LC textures A banded spherulite morphology under polarized optical microscopy was observed.Self-assembled hierar- chical superstructures of the synthesized sugar-containing LCs and LCPs in solution state were also studied.Several kinds of morphologies,such as,platelet,helical twist and spherical vesicle were observed for the sugar-based LCs. These LCs provide a simplified system to explain the chirality transfer from molecular level to macroscopic size.Fur- thermore,some bulky groups,such as,acethylene,phenylacetylene,cinnamoyl and ferrocene was introduced to the hydrophobic end of sugar-based LCs.We found that the helical twist morphology will change from left hand to right hand by introducing the bulky end group on the aliphatic carbon chain.Finally the self-assembly superstructures of sugar-containing LCPs in solution well also investigated.The sugar-containing LCPs form more complex superstruc- tures including nano-spheres and helical nano-fibers.; Several series of sugar-containing liquid crystals(LCs)and liquid crystalline polymers(LCPs)were syn- thesized and characterized.The self-assembly of the sugar-containing LCs and LCPs give rise to a variety of specific LC textures A banded spherulite morphology under polarized optical microscopy was observed.Self-assembled hierar- chical superstructures of the synthesized sugar-containing LCs and LCPs in solution state were also studied.Several kinds of morphologies,such as,platelet,helical twist and spherical vesicle were observed for the sugar-based LCs.
