Porous organic polymers (POPs) are an emerging class of porous materials, having many promising applications in a variety of areas. Among them, covalent triazine frameworks (CTFs) featuring conjugated and porous structures can be well applied in optoelectronics. To achieve high optoelectronic performance, usually the design and synthesis of CTFs based on appropriate building blocks is critical. Here we report the synthesis of two fluorescent CTFs based on typical fluorescent building blocks, in which CTF-Py constructed from a pyrene (Py) building block was reported for the first time, showing prospective applications in the sensing of nitroaromatics with high sensitivity, and photocatalytic water splitting and carbon dioxide reduction with high performance in comparison with other porous organic materials. 多孔有机聚合物(POPs)是一类新兴的多孔材料, 在多个领域有着广阔的应用前景. 其中, 具有共轭多孔结构的共价三嗪框架(CTFs)在光电子学中具有良好的应用前景. 为了获得高性能的光电材料, 通常基于合适的构建单元设计是构建CTFs至关重要的途径. 本文报道了两种基于典型荧光构建单元的新型荧光CTF的合成, 其中CTF-Py是首次由芘(Py)构建单元构建而成, 在高灵敏度硝基芳烃传感中显示了一定的应用前景, 并在光催化水分解和二氧化碳还原中展现了良好的催化性能.
