Abstract Two‐dimensional covalent organic frameworks (2D COFs) are crystalline porous materials with predesignable topologies, periodic structures, and tunable functionalities constructed from molecular building blocks through bonds. Their modular design allows for the integration of various functionalities, making 2D COFs highly suitable optoelectronic applications. COF films have emerged to integrate into devices, avoiding low dispersibility poor processability powder materials. Interfacial polymerization is a blooming method fabricate at liquid‐solid, liquid‐liquid, water‐air, solid‐gas interfaces. Obtaining high‐quality key exploring their performance in electronics. This review first discussed synthetic strategies constructing oriented by interfacial polymerization, including general nucleation‐growth process, field‐induced assembly nucleation‐growth, other methods. The applications electronic devices reviewed, photodetectors, transistors, electrochromic resistive memory, neuromorphic devices. Finally, challenges perspectives synthesizing outlined.

Abstract Photocatalytic conversion of waste carbon dioxide (CO 2 ) into fine chemicals is crucial for solar energy utilization and mitigating the global climate crisis. Artificial photocatalysis based on integrated biocatalyst offers a promising approach converting CO high‐value chemicals. The development metal‐free heterogeneous photocatalysts has gained significant attention as sustainable platform practical artificial photocatalytic systems. In this study, we report one‐pot synthesis covalent triazine‐based (CTPs) their applications. as‐synthesized CTPs exhibit excellent performance, achieving generation HCOOH from with yield 224.85 μM. underlying photo‐physical properties were investigated by using systematic time‐resolved laser spectroscopies. These measurements reveal that formation long‐lived charge transfer state in at late time window strongly correlated enhanced efficiency delaying ultrafast recombination. This study will serve benchmark example wide applications fixation chemical production.
