Abstract

The covalent organic frameworks (COFs) with olefin linkages are attractive materials for nonlinear optics due to their small energy band gap and large π-electron separation domain. In this paper, a post-synthetic modification (PSM) by applying a heck coupling reaction on olefin-linked COFs was applied for the first time to obtain five functionalized triazine-based covalent organic framework materials. The synthesized materials were tested for their relevant photophysical and electrochemical properties, and their third-order nonlinear optical properties were tested using the Z-scan technique. The experimental results indicate that the post-modified COF (W4-2) exhibits third-order nonlinear polarizability χ3 that is 1.51 times higher than the unmodified COF (W4).
