Abstract
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.
