摘要:
A strategy for the development of visible-light-sensitive organic cage structures is reported. Enantiomeric imine cages with optical and electrochemical properties are developed employing perylene diimide (PDI) and tetraphenylethene subunits using dynamic covalent imine chemistry. Polycyclic aromatic hydrocarbons are encapsulated efficiently in the imine cage, and the guests interact with PDI units via supramolecular pi-pi interactions. Visible-light-driven Smiles rearrangement of 2-aryloxybenzoic acids to aryl salicylates is achieved with high efficiency in the presence of the imine cage as the catalyst.
