Using Gas Molecules to Assemble Value-Added Materials through Dynamic Gas-Bridged Bond

Abstract

The conversion and utilization of greenhouse gases and other polluting gases in a green way represents a crucial strategy for developing C₁ chemistry and mitigating the dual crises of energy scarcity and the greenhouse effect. As a class of polyatomic molecules with a relatively simple structure, gas molecules are directly involved in the assembled process as the building blocks, converting them into polymer assemblies under mild and low energy consumption, and constructing recyclable functional assembled materials, which is of great significance to enrich the building block of assembly and promote the sustainable value-added of gas. The dynamic gas bridge is a new way of combining gas with other molecules, it provides the possibility for gas conversion and dynamic assembly. This perspective systematically introduces the formation mechanism and unique physicochemical properties of the dynamic gas bridge, and discusses the latest research progress of dynamic gas-bridged chemistry with a particular focus on three key aspects: gas-regulated assembled system, gas-constructed assembled materials, and green and efficient catalysis. Finally, a perspective on critical challenges and future directions of assembled materials based on dynamic gas bridge chemistry are also highlighted.
