modification (PSM) is a prevalent and powerful strategy to introduce desired
functionalities into covalent organic frameworks (COFs) for functional products,
expediting their applications vastly. Herein, we demonstrate a PSM strategy for
functionalizing brominated COFs via
the well-developed Suzuki-Miyaura cross-coupling. By this protocol, a variety
of functionalities were installed into COFs efficiently, while the
crystallinity and porosity of COFs retained well. As a proof-of-concept,
BrCOF-2 was modified with trifluoromethyl groups to produce a SF6
adsorbent with remarkably enhanced properties. This facile and versatile
approach opens a new door for the synthesis of functional COFs, and greatly
expands the scope of their structural design aiming for various properties and
