Cu(I)-cluster-based Covalent Organic Frameworks with Open Metal Sites and Tuned Microporosity for Efficient C2H2/CO2 Separation

Key Points

• This research aims to explore the effectiveness of Cu(I)-cluster-based COFs in separating C2H2 from CO2 more efficiently.
• Developed two Cu(I)-cluster-based COFs with distinct open metal sites and microporosity.
• Evaluated their separation performance for C2H2 and CO2.
• Utilized various analytical techniques for characterizing the COFs and assessing separation efficiency.
• The Cu(I)-cluster-based COFs showed significantly improved separation rates for C2H2 compared to traditional methods.
• Achieved a separation factor of over X for C2H2/CO2 under specific conditions.
• Demonstrated tunable microporosity enhanced the selective adsorption of C2H2.
