A quinazolinone-linked covalent organic framework with an intrinsic N–N bond for efficient palladium nanocatalysis

Abstract

We report a quinazolinone-linked covalent organic framework (AABH-TFBT-COF) featuring an intrinsic N–N bond embedded within the heterocyclic backbone. This framework stabilizes Pd nanoparticles and serves as a highly active and recyclable catalyst for Suzuki–Miyaura cross-coupling, highlighting the potential of heterocycle-embedded N–N linkages in heterogeneous catalysis.
