An organobase assisted approach is adopted to synthesize a series of β-ketoenamine-linked covalent organic frameworks (COFs), exhibiting superior crystallinity and porosity in comparison with those using an acidic catalyst. The quality promotion arises from the organobase-modulated transimination that favors the reaction kinetics for self-improvement of ordered structures.
采用有机碱辅助方法合成了一系列β-酮烯胺连接的共价有机框架（COF），与使用酸性催化剂合成的COF相比，其结晶度和孔隙率更高。质量提升源于有机碱调节的转亚胺化反应，该反应有利于有序结构自我完善的反应动力学。
