摘要	Photocatalytic conversion of CO2 into value-added chemicals under visible light irradiation is very appealing but challenging due to the easy recombination of hole-electron pairs in traditional photocatalysts. & pi;-& pi; stacking interactions can be favorable for efficient separation and transfer of photo-irradiated charges to promote photocatalysis, but are rarely studied in crystalline porous frameworks like covalent organic frameworks (COFs). Herein, we report a series of thienothiophenes-porphyrin based 2D COFs, denoted as TT-Por(M)-COF (M = 2 H/ Co/Cu/Ni), which show enhanced intralayer and interlayer charge separation and migration due to the donoracceptor heterojunctions and & pi;-stacked columns. The TT-Por(Co)-COF achieves enhanced CO evolution rate than COF-366-Co without the heterojunctions and & pi;-columns (10.05 mmol g-1 h-1 versus 7.10 mmol g-1 h-1) under visible light irradiation. This work not only shows the important role of & pi;-& pi; stacking interactions of COFs for CO2 conversion, but also provides insight into the mechanistic aspect for photocatalysis.
