Abstract

Post-synthetic modification strategy is presented to extend the pi-system of covalent organic framework (COF) backbone giving access to boronic ester based pyrene-fused azaacene COFs. Optimized catalyst-free reaction conditions yield COFs post-synthetically modified with up to 33% conversion and corresponding intriguing optical properties. The presented chemistry is expected to find application in post-synthetic tailoring of the optical properties of COFs.
