Synthesis Of Zeolitic Tetrazolate-Imidazolate Frameworks (Ztifs) In Ethylene Glycol

Ethylene glycol (EG) as a universal solvent is used to reproducibly synthesize zeolitic tetrazolate imidazolate frameworks (ZTIF-11 to -13) in high yields. The phase-pure frl-type ZTIF-11 is confirmed to be permanently porous and shows high chemical stability as well as remarkable performance in the selective separation of CO2 at ambient temperature.
