报告内容摘要：
Producing carbon-neutral solar fuels presents a promising approach toward confronting the global warming and the fossil fuels crises from the source. Integrating all the necessary molecular components into a durable artificial system for photocatalysis is a long-term goal for scientists. Supramolecular assemblies play critical roles in natural photosynthesis that supplied most energy of the Earth by far.1 Protein and lipids as nature-made scaffolds play critical roles in photosynthetic organelles, such as plant chlorophyll, which integrate light harvesting, excitons/charges transport and catalysis in one body. Mimicking the natural behavior of light harvesting complexes that precisely manipulate the photocatalytic process is a great challenge.2 Herein, we synthesized a series of novel block co-polymers with polyferrocenyldimethylsilane (PFS) as a crystallizable core-forming block and photosensitizers or catalysts embedded polymer as corona-forming block. Based on tailored hierarchical micelle architectures using living crystallization-driven self-assembly (CDSA), a noble metal free integrated photocatalytic system was constructed. Photocatalytic production of hydrogen is observed in the micro-environment of the scaffold and the material is easily made. These artificial assemblies powered by visible-light are highly stabile, efficient, and recyclable at ambient temperature and pressure. This strategy provides unique insight for the design of artificial photocatalytic materials.
