“…In another work, 2D porphyrin imine‐based COFs possessing donor–acceptor (D‐A) units were prepared, and their catalytic activity was examined in the selective oxidation of sulfides and reductive dehalogenation of 2‐bromoacetophenone ( Figure ). [ 164 ] Under visible‐light conditions, the selective oxidation of methylphenyl sulfide was studied with PTBC‐Por COF, observing 97% conversion with 99% selectivity. On the other hand, the reductive dehalogenation of 2‐bromoacetophenone using PTBC‐Por COF as photocatalyst afforded 99% conversion with 82% of yield.…”

Organic photochemistry is intensely developed in the 1980s, in which the nature of excited electronic states and the energy and electron transfer processes are thoroughly studied and finally well‐understood. This knowledge from molecular organic photochemistry can be transferred to the design of covalent organic frameworks (COFs) as active visible‐light photocatalysts. COFs constitute a new class of crystalline porous materials with substantial application potentials. Featured with outstanding structural tunability, large porosity, high surface area, excellent stability, and unique photoelectronic properties, COFs are studied as potential candidates in various research areas (e.g., photocatalysis). This review aims to provide the state‐of‐the‐art insights into the design of COF photocatalysts (pristine, functionalized, and hybrid COFs) for organic transformations. The catalytic reaction mechanism of COF‐based photocatalysts and the influence of dimensionality and crystallinity on heterogenous photocatalysis performance are also discussed, followed by perspectives and prospects on the main challenges and opportunities in future research of COFs and COF‐based photocatalysts.

“…[ 310 ] The effectively combined ability of charge transfer, photogenerated electron‐hole pairs separation, and high conductivity impaired D‐A COF materials with potential applications in photo‐electrocatalysis. [ 308,311‐316 ] Hence, the electron‐deficient benzothiazole acceptor unit was incorporated into the sp 2 fully π‐conjugated BTH‐3 COFs backbone. This strong D‐A effect endows the COFs with an attractive photocatalytic performance with an HER of 15.1 mmol·h –1 ·g –1 under visible light irradiation.…”

2D covalent organic framework (2D-COF), a modular three-dimensional material, is easily influenced by the component module. The assembly of different functionalized modules gives 2D-COF unique performance. The modular structure not only allows for customization but also allows for variety, which gives 2D-COF a wide range of functions. Hence, many building blocks with catalytic, ligand, semiconductor, luminescent, and redox centers are integrated into the COF scaffold. The connection and assembly of such modules determine the nature of the final block material. The intra-layer connections of the modules form a monolayer mesh chemical structure, and the subsequent stacking of the monolayer mesh structure produces the final crystalline porous material-2D-COF. This review describes in detail the potential of COF materials as optoelectronic materials and our understanding of optoelectronic processes, starting from monolayer reticulation chemistry to final 3D stacked structures, thus establishing a new paradigm for the rational design of well-defined novel 2D-COF optoelectronic materials and devices.

“…Covalent organic frameworks (COFs) are a new type of POPs, which are skillfully constructed by strong covalent bonds with organic building units. [124][125][126][127] In particular, 2D COFs have aroused considerable interest from researchers because of their important application value in the eld of energy storage. [128][129][130][131] The transport through the frameworks greatly increases the migration rate of lithium ions and electrons, which greatly enhances the reaction kinetics of the active sulfur.…”
