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.

通过简便的方法制造具有可控形态的共价有机骨架 (COF) 仍然是一项重大挑战。在本通讯中，基于醛基功能化的六胺基单体合成了一系列具有不同形貌的亚胺连接的共价有机框架（PD-TPA COF），并提供了一种新的形貌控制 PD-TPA COF 的策略。探讨了溶剂和催化剂对 PD-TPA COF 形貌的影响。通过动态调节混合溶剂的比例，观察到 PD-TPA COF 的形貌发生显着变化。COF 的形态和表面可以通过催化剂的性质和浓度进行调整。
