pNJU-319Fe显示出688 μmol g-1的CO产率,比未改性的NJU-3119Fe相比增加了2.5倍。相关工作以“Postsynthetic Annulation of Three-Dimensional Covalent Organic Frameworks for Boosting CO2Photoreduction”为题发表在国际著名期刊Journal of the American Chemical Society上。
The design and synthesis of three-dimensional covalent organic frameworks (3D COFs) have still been considered as a big challenge. Here we report the design and synthesis of an AIEgen-based 3D COF (3D-TPE-COF), with a high surface area (1084 m2 g
Covalent organic frameworks (COFs) are a class of porous polymer in which organic building blocks are precisely integrated into extended structures with periodic skeletons and ordered pores1. COFs are a new type of crystalline porous solids with well-defined two-dimensional (2D) or three-dim...
3D-ICOF-1三维离子型共价有机框架材料 有机共价框架( covalent organic frameworks , COFs )是一类新型晶态有机多孔材料,具有结构可设计和功能可调控的特点,在异相催化、能源转换与存储、气体吸附和分离等领域。 3D
近年来,氢键有机框架材料(Hydrogen-Bonded Organic Frameworks, HOFs)的开发和应用越来越受到人们的关注。与传统的结晶性多孔材料MOFs(Metal-Organic Frameworks)、ZIFs(Zeolitic Imidazolate Frameworks)、COFs(Covalent Organic Frameworks)等相比,HOFs材料由非共价的分子间作用力(氢键、π-π堆积等)连接而成,具有低密度、...
