A supramolecular dual-donor artificial light-harvesting system with efficient visible light-harvesting capacity

The design and fabrication of highly efficient artificial light-harvesting systems (LHSs) are of great importance in supramolecular chemistry and materials science. Benefitting from the convenient construction process of supramolecular self-assembly, herein, a dual-donor artificial LHS was efficiently constructed through hierarchical self-assembly approaches involving metal-ligand coordination interactions, host-guest interactions and hydrophobic interactions. Notably, compared to the model single-donor artificial LHS with only one donor chromophore, the prepared dual-donor artificial LHS exhibited higher energy transfer efficiency and antenna effects. This research provides an efficient strategy for the construction of artificial LHSs with high energy transfer efficiency and antenna effects.
