Summary: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. A series of high-quality β-ketoenamine-linked covalent organic frameworks are synthesized by using organobases as modulators under solvothermal conditions.
