摘要

The assembly of pi-conjugated molecule-based supramolecular micro/nanostructures is acknowledged as a versatile platform correlating supramolecular chemistry and soft matter science, wherein those with a spherical morphology are a topic of general concern. Most of the existing protocols, however, work only in some specific scenarios. It still remains a formidable challenge to initiate a general protocol for supramolecular micro/nanospheres of desired pi-conjugated molecules. We herein report our new findings that numerous porphyrins and some other pi-conjugated molecules, including phthalocyanine, anthracene, and naphthalenediimide derivatives, could be assembled to form micro/nanospheres via an oil-in-water-mediated surfactant-assisted assembly. As an example for the functionalization of the as-assembled structures, we show that a supramolecular light-harvesting antenna system with regard to photo-semiconductor-based heterogeneous photocatalysis could be achieved using porphyrin spheres. It is disclosed that the distinct chromophoric arrangements, which endow our porphyrin spheres with different photoinduced electron-hole separation capability, contribute greatly to their superior/inferior catalytic performances. Our new method might initiate a general method for advanced micro/nanospheres of desired pi-conjugated molecules and desired functions.
