Gas-constructed assembled materials: a sustainable way for transforming gas into value-added products

The conversion and utilization of greenhouse gases and other polluting gases in an environmentally friendly 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 assembly process as the building blocks. Their conversion into polymer assemblies and recyclable functional assembled materials under mild and low-energy consumption is of great significance for enriching the building blocks of assembly and promoting the sustainable value-added use of gas. The dynamic gas bridge is a new way of combining gas with other molecules, providing 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 in 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 the critical challenges and future directions of assembled materials based on dynamic gas bridge chemistry is also highlighted.
