Covalent organic frameworks (COFs) attract significant attention due to their ordered, crystalline, porous, metal-free, and predictable structures. These unique characteristics offer great opportunities for the diffusion and transmission of photogenerated charges during photocatalysis.

2024年1月24日 · Herein, based on reticular chemistry, we rationally designed a series of three-motif molecular junction type COFs, which formed dual photosensitizer coupled redox molecular junctions containing multifunctional COF photocatalysts.

Covalent organic frameworks (COFs) are crystalline porous polymers formed by a bottom-up approach from molecular building units having a predesigned geometry that are connected through covalent bonds. They offer positional control …

2020年1月22日 · Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with permanent porosity and highly ordered structures. Unlike other polymers, a significant feature of COFs is that they are structurally predesignable, synthetically controllable, and functionally manageable.

2024年5月21日 · Experimental and theoretical results indicate that interlayer Co-imine N motifs on the donor 1-acceptor-donor 2 structures facilitate the formation of a highly separated electron-hole state, which effectively induces the oriented electron transfer from dual electron donors to Co centers, achieving an enhanced CO 2 activation and reduction.

2024年3月18日 · By comparing the crystal structure of COF-300, COF-304, COF-305, and their molecular model compounds, we conclude that the structural complexity of COF-305 originates from the TAM motif...

2020年10月22日 · In the realm of porous materials, layered COFs — also referred to as two-dimensional COFs — are a particular case whose porosity and long-range order arise from the spontaneous assembly of extended...

新型卟啉基共价有机框架（cof）纳米光敏剂，结合i型和ii型光动力治疗特性，通过分子内供体-受体结合和硫取代增强isc能力，显著提升活性氧（ros）生成效率，为乏氧肿瘤的光动力免疫治疗提供创新解决方案。

2023年1月15日 · In this review, we summarize the different methods for the synthesis of COFs, such as solvothermal synthesis, microwave synthesis, ionothermal synthesis, room temperature solution synthesis, mechanochemical synthesis and interfacial synthesis firstly. Then, the structural features of COFs such as diversity, tailorability, stability and porosity.

2024年8月27日 · We highlight the design principles of tailor-made functional COFs through compositional tuning, synthetic and structural modulations, and topological diversification. By precisely integrating building units with specific functions, we have developed various COFs, including charged, optoelectronic tunable, radical, and switch COFs.
