反拓扑盘状液晶研究进展

A new design principle for liquid crystals is introduced in this article, namely shape persistent arylacetylene macrocycles with intraannular orientation of the alkylchains. They are composed of a rigid periphery and flexible side groups that point to the inside (inverted liquid crystals) different from all the classic design principle for discotic liquid crystals. The influence of the orientation, types and size of the ring substituents on their liquid crystalline behaviors are discussed. All the investigation support that this design principle is rather general and can be used for design more complex supra structure in the future.
