Room‐Temperature Synthesis of Covalent Organic Framework (COF‐LZU1) Nanobars in CO2/Water Solvent

The development of facile, rapid, low‐energy, environmentally benign routes for the synthesis of covalent organic frameworks (COFs) is of great interest. This study concerns the utilization of water containing dissolved CO2 as a solvent for the room‐temperature synthesis of COF. The as‐synthesized particles, denoted COF‐LZU1, combine advantages of good crystallinity, nanoscale size, and high surface area, which suggests promising application as a support for heterogeneous catalysts. Moreover, this versatile CO2‐assisted method is also applicable for the room‐temperature synthesis of Cu−COF‐LZU1. This method gives rise to new opportunities for fabricating COFs and COF‐based materials with different compositions and structures.
