Figure Abstract

Caption

A series of three-dimensional porous aromatic frameworks (3D-X-TB-PAFs (X = TEPE, TEPM, SPF)) are constructed by introducing Tröger base (TB) and stereo aromatic alkynes. TB brings intramolecular polarization and electron trap sites, which cooperate with 3D hierarchical architecture to regulate carrier recombination and customize reaction sites. The energy barriers for CO2 activation and conversion are decreased on TEPE-TB-PAF, which exhibits impressive photocatalytic CO2 reduction performances with near-unity selectivity of CO and H2O oxidation performances.
