Abstract
Abstract The establishment of green and environmental friendly sunlight‐driven organic reactions has received increasing attention since the 21st century. By virtue of their functional designability, micromesoporous structure, and thermal/chemical stability, porous organic polymers (POPs) have exhibited enormous promise in photocatalytic organic reactions as ideal potential alternatives to conventional small molecule and inorganic semiconductor catalysts. In particular, amorphous POPs are simplified in terms of preparation conditions and process flow. Herein, various amorphous POP materials based on polymers of intrinsic microporosity, hypercrosslinked polymers, conjugated microporous polymers, and porous aromatic frameworks are reviewed, while typical synthetic strategies are briefly introduced. It also highlights an overview of the research progress in photocatalytic oxidation, coupling, reduction, cycloaddition, and polymerization reactions at home and abroad in recent years. Finally, the challenges and prospects for future research on amorphous POPs are presented.
