Abstract

Inorganic-organic hybrids, particularly the ones with an intercalated structure, have attracted substantial attention, because they can potentially bring unique properties combining distinct features of organic and inorganic components within a single molecular composite. A number of approaches to achieve intercalation have been developed based on different reaction/interaction mechanisms, and intercalation reactions have been carried out at various interfaces. After all, the intercalation methodologies developed so far are all based on a two-step process: formation of layered materials first and subsequent intercalation by guest species, which requires extra time and efforts, and some desirable guest molecules may not be able to be intercalated into the host because of size mismatch, lack of driving force, etc. Overall, such a two-step process appears to be very primitive compared to the simultaneous growing of biological layered compounds in the nature. In this presentation, a new approach to directly prepare intercalation compounds via one-pot in situ synthesis is introduced. The synthesized intercalation compounds with various combinations of host and guest were characterized. Its reaction mechanism was investigated, which is expected to guide the future synthesis of more sophisticated biological hybrid materials. Potential applications of selected examples are explored. The implication of the present findings is discussed.
