ConspectusCovalent triazine frameworks (CTFs) are a novel class of nitrogen-rich conjugated porous organic materials constructed by robust and functional linkages, which possess unique structures excellent physicochemical properties. They have demonstrated broad application prospects in gas/molecular adsorption separation, catalysis, energy conversion storage, etc. In particular, crystalline CTFs with well-defined periodic molecular network regular pore channels can maximize the utilization features promote deep understanding structure-property relationship. However, due to poor reversibility basic reaction for constructing unit traditional harsh synthesis conditions, it remains considerable challenge synthesize diverse structures, there is still significant lack their polymerization mechanism, limits precise structural design, large-scale preparation, practical applications. As building block bulk CTFs, two-dimensional polymers (2D-TPs) ideally single-atom thickness also aroused intensive interest ultrathin 2D sheet morphology flexibility, fully exposed plane active sites, dispersibility processability. efficient scalable production high-quality 2D-TPs investigation properties functions remain largely unexplored.In this Account, we summarize our recent contributions exploration 2D-TPs.

Abstract Covalent organic frameworks (COFs) feature π‐conjugated structure, high porosity, structural regularity, large specific surface area, and good stability, being considered as ideal platform for photocatalytic application. Although single COFs have achieved significant progress in photocatalysis benefiting from their distinctive properties, the COFs‐based hybrids provide an extraordinary opportunity to achieve superior performance. From perspective of carrier transfer mechanism, a systematic summary based on other functional materials (metal atoms, metal clusters/nanoparticles, inorganic semiconductors, metal–organic frameworks, polymers) can offer valuable guidance design hybrids. In this review, mechanism hybrid (such Schottky junction, type II heterojunction, Z‐scheme S‐scheme heterojunction) is briefly introduced. Subsequently, performance water splitting, CO 2 reduction, pollutant degradation are comprehensively reviewed. Specifically, separation different types highlighted. Finally, challenges prospects envisaged. The insights presented review expected be helpful rational obtain outstanding activity. image

Recent progress in conjugated polymer photocatalysts has opened avenues for enhancing photocatalytic hydrogen production (PHP) activity through structural design. This study highlights the impact of acceptor-to-donor feed ratio on PHP copolymers, influencing their energy level structures. Five porous polymers (CPPs) were synthesized by adjusting molar ratio. Notably, at a 2:1 ratio, demonstrated high evolution rate (HER) 61.9 mmol g−1 h−1 under full arc irradiation without co-catalysts and an apparent quantum yield (AQY) 7.77% 475 nm. However, further increasing proportion donor unit copolymers decreases HER. Experiments theoretical simulation characterized that ratios effectively tune polymer's molecular structure, hydrophilicity, band gap, generation transport efficiency photo-induced charge carriers, ultimately affecting kinetics efficiency. research demonstrates tuning structure chemical compositions CPPs statistical copolymerization significantly impacts activity.
