Pyridinium Containing Amide Based Polymeric Ionic Liquids for CO2/CH4 Separation

Herein, we describe the design and synthesis of novel pyridinium containing amide based poly(ionic liquid)s (PAPILs) for CO2 capture and separation. Additionally, a new and unique crystal structure of pyridinium containing diamine monomer [MDAP][TFSI] is also presented. PAPILs reveal potential for CO2/CH4 separation and isosteric heat of adsorption in the physisorption range.
