Abstract Photocatalysis leverages solar energy to overcome the thermodynamic barrier, enabling efficient chemical reactions under mild conditions. It can greatly reduce reliance on traditional sources and has attracted significant research interest. Reticular materials, including metal‐organic frameworks (MOFs) covalent organic (COFs), represent a class of crystalline materials constructed from molecular building blocks linked by coordination bonds, respectively. function as heterogeneous catalysts, combining well‐defined structures high tailorability akin homogeneous catalysts. In this review, regulation light absorption, charge separation, surface in photocatalytic process through precise molecular‐level design based features reticular is elaborated.

Abstract Recent interest has surged in using heterogeneous carriers to boost synergistic photocatalysis for organic transformations. Heterogeneous catalysts not only facilitate enhancement of distinct catalytic centers compared their homogeneous counterparts, but also allow the easy recovery and reuse catalysts. This mini‐review summarizes recent advancements developing carriers, including metal–organic frameworks, covalent–organic porous polymers, others, reactions. The advantages materials catalysis originate from ability provide a high surface area, enhanced mass transport, offer tunable chemical structure, ensure stability active species, enable Both photosensitizers can be intricately incorporated into suitable create dual photocatalysts Notably, experimental evidence reported cases shown that efficacy often surpasses analogues. performance is attributed proximity confinement effects provided by nature carriers. It expected will versatile platform integrating diverse catalysts, thus exhibiting superior across range transformations appealing prospect industrial applications.

Photocatalytic hydrogen peroxide (H2O2) production using conjugated polymers as photocatalysts is a green and sustainable approach to synthesizing H2O2. Nevertheless, the efficiency still hindered by inefficient charge separation transfer dynamics. Herein, series of coplanar 2D ladder with different substituents were reported metal-free for artificial photosynthesis Detailed experimental theoretical investigations reveal that skeleton strong electron-withdrawing could profoundly facilitate transfer. Possessing these notable merits, cyano-substituted polymer (PAE-CN) exhibits remarkable photocatalytic performance on H2O2 evolution. This study contributes development effective tailored potential applications in photosynthesis.

Metal-anchored covalent organic frameworks (COFs), as a class of significant derivatives COFs, are widely used heterogeneous catalysts in diverse chemical reactions. However, they typically synthesized via post-treatment strategies, which often lead to the decline COF crystallinity, decrease porous properties, instability catalytic performances, generation additional waste, and consumption excess time energy. In this work, we demonstrate an approach construct metal-functionalized one-pot method induced by γ-ray radiation. Specifically, copper-coordinated was situ irradiating mixture monomers copper salt under ambient conditions. Interestingly, initial Cu

Abstract Covalent triazine frameworks (CTFs) are promising heterogeneous photocatalyst candidates owing to their excellent stability, conjugacy, and tunability. In this study, a series of CTFs decorated with different substituents (H, MeO, F) were synthesised utilised as photocatalysts for C−H activation reactions. The corresponding optoelectronic properties could be precisely regulated by the electronic effects in nanopore channels CTFs; these effective organic synthesis due unique structures properties. Methoxy‐substituted CTF (MeO‐CTF) exhibited extraordinary catalytic performance reusability functionalization constructing an donor‐acceptor system, achieving highest yield photocatalytic C3–H hydroxylation 2‐phenylimidazole[1,2‐α]pyridine. This strategy provides new scaffold rational design efficient synthesis.
