General synthesis of covalent organic frameworks under ambient condition within minutes via microplasma electrochemistry approach.

ABSTRACT: Covalent organic frameworks (COFs) are typically synthesized using solvothermal conditions with high temperature and long reaction time (≥120 °C, >72 h). Herein, we report a general and rapid microplasma electrochemistry strategy to synthesize COFs under ambient conditions. A series of flexible imine-bond COFs with high-crystallinity were prepared in minutes via this method, which showed 1000-fold higher space-time yield than solvothermal method. This approach also achieved the preparation of COFs with diverse linkages including rigid imine, hydrazone, β-ketoenamies and azine linkages. Moreover, four types of imine-based COFs were successfully synthesized in aqueous acetic acid, which avoided the use of harmful organic solvents, indicating that microplasma method is green and versatile for
