Photosynthesis is the process through which living plants utilize photosynthetic pigments,such as chloro-phyll,to convert CO2 and water into organic compounds and release O2 under visible light.In this study,we have successfully constructed a fluorescent supramolecular polymer(P5Py2/Zn/Gen)n by em-ploying orthogonal pillar[5]arene-based molecular recognition and metal ion coordination.Within the supramolecular polymer,the guest molecule Gen unit acts as a light-harvesting moiety,as the ACQ effect is inhibited by host-guest interactions,while the(Py)2/Zn center serves as a catalytic site.By employing this orthogonal self-assembly strategy,we have enhanced the stability of both the donor and acceptor in catalyzing the reduction of p-nitrophenol to p-aminopheno.Moreover,this photocatalyst can be reused at least 5 times without significant conversion loss.These findings provide a pathway for constructing a recyclable artificial LHS that mimics the entire photosynthesis process.
