Flexible metal-organic frameworks for gas storage and separation

Area of Science:

• Materials Science
• Chemistry
• Nanotechnology

Background:

• Flexible metal-organic frameworks (MOFs) are gaining attention for their adaptable structures and responses to external stimuli.
• Research primarily focuses on gas storage and separation, yet lacks systematic summarization.

Purpose of the Study:

• To review the development of flexible MOFs.
• To analyze structural transformations under temperature, pressure, and guest molecule stimuli.
• To summarize applications in gas storage and separation.

Main Methods:

• Literature review of flexible MOF research.
• Analysis of structural dynamics under various external stimuli.
• Evaluation of MOF performance in gas storage and separation.

Main Results:

• Flexible MOFs demonstrate reversible structural changes and dynamic responses.
• External stimuli like temperature, pressure, and guest molecules induce significant structural transformations.
• Tunable pore size and shape, breathing phenomena, and large surface area are key characteristics.

Conclusions:

• Flexible MOFs offer unique opportunities for performance fine-tuning through controlled pore modification.
• Their properties make them highly suitable for advanced gas storage and separation technologies.
• Future prospects for flexible MOFs in these applications are promising.
