研究目的
Investigating the development of a new photoswitchable host-guest system based on a non-photoresponsive hydrogen-bonded amide macrocycle and pyridinium salts for reversible guest capture and release via proton transfer by light stimulus.
研究成果
The study successfully developed a new photoresponsive host-guest system based on a non-photoresponsive two-dimensional macrocyclic host. The photo-switchable complexation was realized using a combination of a H-bonded cyclo[6]aramide as host, 1-MEH as photoacid, and protonated pyridinium salts as guest, demonstrating reversible guest capture and release under light irradiation and dark conditions. This system may find applications in constructing photoacid-driven molecular machines and switchable supramolecular materials with photoresponsive properties.
研究不足
The study is limited by the need for specific functionalities on synthetic frameworks for photoresponsive systems and the reliance on the synthetic accessibility and feasibility of molecular modification. Additionally, the photo-switchable complexation requires a guest with its conjugate base having moderate basic nature.
