Even today, the problem of greenhouse gas emissions and recycling endanger human health continuously. The dynamic structure of the flexible MOFs (metal-organic frameworks) allows them to change their structure in response to external stimuli. And a fresh approach to reducing greenhouse gas emissions comes from using flexible frames for gas absorption, notably in the area of lower energy and highly selective gas separation. This review starting from the design and improvement of flexible MOFs summarizes some excellent cases in carbon dioxide capture. Finally, the potential applications of flexible MOFs are classified and briefly analyzed.
