Abstract

Proton transport via a dynamic chemistry method is an essential pathway in both biology and chemistry. In chemical catalysis, proton-shuttling catalysts were developed by mimicking the proton-transport processes in biological systems. However, YH (Y = O, N, S, etc.) units are typically essential for enabling proton transport in these catalysts. Herein, we present a novel strategy for constructing in situ reversible proton-shuttling covalent organic framework catalysts, avoiding the need for Y–H functional groups. Specifically, we demonstrate that the 2D bis(imino)pyridine Cu-bipy-COF material could transform to a water proton-shuttling catalyst by using the reversible interconversion between imine and hemiamine. This catalyst could effectively catalyze the hydration of benzonitrile in neat water without the use of a toxic organic solvent.
