Abstract Covalent organic frameworks (COFs) face limited processability challenges as photoelectrodes in photoelectrochemical water reduction. Herein, sub‐10 nm benzothiazole‐based colloidal conjugated reticular oligomers (CROs) are synthesized using an aqueous nanoreactor approach, and the end‐capping molecular strategy to engineer electron‐deficient units onto periphery of a CRO nanocrystalline lattices (named CROs‐Cg). This results stable processable “electronic inks” for flexible photoelectrodes. CRO‐BtzTp‐Cg CRO‐TtzTp‐Cg expand absorption spectrum into infrared region improve fluorescence lifetimes. Heterojunction device engineering is used develop interlayer heterojunction bulk (BHJ) with hole transport layer, electron main active layers, CROs/CROs‐Cg or one‐dimensional (1D) electron‐donating polymer HP18 mixed solution via spinning coating. The ITO/CuI/CRO‐TtzTp‐Cg‐HP18/SnO 2 /Pt photoelectrode shows photocurrent 94.9 µA cm ‒2 at 0.4 V versus reversible hydrogen electrode (RHE), which 47.5 times higher than that ITO/Bulk‐TtzTp. Density functional theory calculations show reduced energy barriers generating adsorbed H* intermediates increased affinity CROs‐Cg. Mott‐Schottky charge density difference analyses indicate enhanced carrier densities accelerated transfer kinetics BHJ devices. study lays groundwork large‐scale production COF nanomembranes structures, offering potential cost‐effective, printable systems.

Abstract Covalent organic frameworks (COFs), characterized by their unique ordered pore structures, chemical diversity, and high degree of designability, have demonstrated immense application potential across multiple fields. However, traditional synthesis methods often encounter challenges such as low crystallinity uneven morphology. The introduction surfactants has opened up new pathways for the COFs. Leveraging intermolecular interactions self‐assembly properties, can effectively regulate nucleation, growth processes, ultimate structure properties This paper systematically reviews latest research achievements future trends in surfactant‐assisted COF synthesis, emphasizing crucial role key additives preparation Surfactants not only facilitate uniform nucleation COFs, enhancing structural order products but also enable precise diverse regulation dimensionality, morphology, Furthermore, influencing dispersion processability enhance practicality workability. Finally, presents some prospects opportunities this emerging area.

Abstract A substantial challenge in employing covalent organic frameworks (COFs) for photoelectrochemical (PEC) water splitting lies improving their solution‐processability while concurrently facilitating the transfer of charges and mass to catalytic sites. Herein, we synthesize a solution‐processable conjugated reticular oligomers (CROs), further embed ruthenium (Ru) into CRO, forming CRO‐Ru with homo‐nuclear hetero‐atomic. Thereafter, CRO construct an organic–organic heterojunction membrane at nanoscale. This design achieves perfect lattice matching, significantly reducing energy barrier transfer, effectively lowering recombination rate charge carriers. The optimized photocathode, CuI/CRO‐Bpy:CRO‐Bpy‐Ru‐1:1+P3HT/SnO 2 /Pt, exhibits efficiency 111.0 µA cm −2 0.4 V versus reversible hydrogen electrode (RHE). Compared original bulk COFs CROs, is improved. apparent improvements carrier separation are responsible high PEC activity. In heterojunction, incorporation CRO‐Bpy‐Ru longer excited‐state lifetime built‐in electric field has accelerated photo‐induced electron from conduction band (CB) CRO‐Bpy valence (VB) CRO‐Bpy‐Ru, suppressing charges. These findings offer significant guidance optimization high‐performance catalysts.

Abstract Metal‐coordinated covalent organic frameworks (M‐COFs) have garnered significant attention for their potential in carbon dioxide (CO 2 ) photoreduction. However, the efficient conversion of CO to (carbon monoxide) remains challenging because strong exciton effects from Coulombic interactions electron‐hole pairs within metal‐associated coordination environment. Herein, three benzoxazole (BBO)‐based COF photocatalysts coordinated with cobalt (Co) ions featuring distinct geometries: Co‒N‒O , 3 and Co‒N ‒O are strategically designed. The dissociation is precisely modulated photocatalytic reduction enhanced. Among them, BBO‐COF BPY ‐Co demonstrates a increase production rate 5, 024.87 10, 552.15 µmol g −1 h an improvement selectivity 80% 91%, coupled excellent stability. Spectral characterizations density functional theory (DFT) theoretical calculations elucidate that judicious tuning Co atom environment optimized local electronic structure BBO‐COFs which significantly boosts dissociation, facilitates charge carrier migration framework, mitigates recombination photogenerated pairs, reduce energy barrier rate‐determining step. This study provides insight into pivotal role metal microenvironments enhancing process paving way new strategies regulation COFs.
