“…Recently, Dai and workers reported the effective enhancement of exciton dissociation through the utilization of a COF–COF heterojunction. 88 This achievement was realized by depositing nano-sized colloids of Tp-TTA COF onto tetrahydroquinoline-linked QH-COF. The resulting COF–COF heterojunction displayed a striking enhancement in both transition photocurrent and conductivity in comparison to the individual components.…”

“…Heterojunctions can also be formed between different types of COFs. Dai et al [211] recently synthesized a type of COF-COF heterojunctions by depositing nanostructured TP-TTA COF colloids onto QH-COF. The Tp-TTA/QH heterojunction exhibited stronger electrical conductivity than monomers, indicating an improved charge separation efficiency attributed to the formation of COF-COF heterojunctions.…”

Covalent organic frameworks (COFs) are one type of porous organic materials linked by covalent bonds. COFs materials exhibit many outstanding characteristics such as high porosity, high chemical and thermal stability, large specific surface area, efficient electron transfer efficiency, and the ability for predesigned structures. These exceptional advantages enable COFs materials to exhibit remarkable performance in photocatalysis. Additionally, the activity of COFs materials as photocatalysts can be significantly upgraded by ion doping and the formation of heterojunctions. This paper summarizes the latest research progress on COF‐based materials applied in photocatalytic systems. Initially, typical structures and preparation methods of COFs are analyzed and compared. Moreover, the essential principles of photocatalytic reactions over COFs‐based materials and the latest research developments in photocatalytic hydrogen production, CO2 reduction, pollutants elimination, organic transformation, and overall water splitting are indicated. At last, the outlook and challenges of COF‐based materials in photocatalysis are discussed. This review is intended to permit instructive guidance for the efficient use of photocatalysis based on COFs in the future.

“…COFs are organic porous polymers connected by covalent bonds, resulting in permanent porosity, periodic arrangement, and thermal/chemical stability. [26][27][28][29] Therefore, COFs are widely used in sensing, [30] gas absorption/storage, [31] and catalysis [32] due to the convenience for characterization. Although COFs materials have long-range ordered structures and large specific surface areas, their synthesis conditions are more stringent and the mechanism has not been well revealed.…”

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.
