Organobase modulated synthesis of high-quality β-ketoenamine-linked covalent organic frameworks

An organobase assisted approach is adopted to synthesize a series of beta-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.

Automated summary

Organobase-assisted synthesis results in beta-ketoenamine-linked COFs with superior crystallinity and porosity compared to those using acidic catalysts. The quality enhancement is attributed to the organobase-modulated transimination, which promotes reaction kinetics for self-improvement of ordered structures.
