Oppositely-charged coordination cages form a Type I porous ionic liquid with two pore sizes

Key Points

• This research aims to introduce a new type of porous liquid made from oppositely-charged coordination cages.
• Prepared through ion metathesis of two oppositely-charged coordination cages.
• Characterized for pore sizes and ionic properties.
• Created a Type I porous ionic liquid with distinct pore sizes.
• Demonstrated potential applications in material science.
