2D covalent organic frameworks with built-in amide active sites for efficient heterogeneous catalysis

Chem Commun (Camb). 2019 Nov 28;55(96):14538-14541. doi: 10.1039/c9cc07500c.

Abstract

Benzene-1,3,5-tricarboxamides (BTAs) are versatile building blocks for supramolecular assembly due to the strong intermolecular hydrogen bonding. Herein, a BTA based amine, N1,N3,N5-tris(4-aminophenyl)benzene-1,3,5-tricarboxamide (TABTA), was successfully applied to construct two new amide functionalized covalent organic frameworks (COFs) with apparent crystallinity, which were further applied as efficient catalysts for Knoevenagel condensation.
