研究目的
To explore the mechanism of transmission of chirality from the molecular level to the macro‐ or supramolecular level and the origin of chirality in soft materials, utilizing light as a chiral stimulus to achieve chiral assemblies based on photochromic switches in soft materials such as liquid crystals and polymeric organizations.
研究成果
Light stimuli can be used to induce chirality from achiral systems and/or the inversion of the resultant chiral soft materials such as cholesteric liquid crystals (CLCs), self‐assembled helical supramolecules, or helical polymers. Photochemical helical inversion is achieved with chiral liquid crystals and polymers based on intrinsically chiral photoresponsive dopants with a certain handedness, and it also photochemically switches to the other handedness by UV or visible light irradiation in a reversible manner.
研究不足
The precise prediction of which system would provide certain targeted chiroptical or mechanical properties remains a challenge. The interplay of ongoing efforts to reveal the underlying principle linking molecular events and the macroscopic phenomena and to develop novel chiral functions from photochromic switches is still under exploration.
