摘要：

A photoactive covalent organic framework (COF) was built from metalloporphyrin and bipyridine monomers and single-atomic Pt sites were subsequently installed. Integrating photosensitizing metalloporphyrin and substrate-activating Pt(bpy) moieties in a single solid facilitates multielectron transfer and accelerates photocatalytic hydrogen evolution with a maximum production rate of 80.4 mmol h-1 gPt-1 and turnover frequency (TOF) of 15.7 h-1 observed. This work demonstrates that incorporation of single-atomic metal sites with photoactive COFs greatly enhances photocatalytic activity and provides an effective strategy for the design and construction of novel photocatalysts. Integrating photoactive metalloporphyrin and single-atomic Pt(bpy) moieties in a single covalent organic framework facilitates multielectron transfer and accelerates photocatalytic hydrogen evolution. with a maximum turnover frequency of 15.7 h-1 observed. image
