摘要：

Fabricating covalent organic frameworks (COFs) with controllable morphology by a facile approach remains a significant challenge yet. In this communication, series of imine-linked covalent organic frameworks (PD-TPA COFs) with different morphology were synthesized based on hexamine-based monomer functionalized with aldehyde groups, and a novel strategy for the morphology control PD-TPA COFs was provided. The effects of solvent and catalyst on the morphology of PD-TPA COFs were explored. A remarkable change in the morphology of PD-TPA COFs was observed through dynamically modulating the proportion of mixed solvent. And the morphology and surface of COFs can be tuned by the nature and concentration of catalysts.
