摘要
Crystalline peptide Ni(II)-macrocycles (BF4- salt) exhibited moderate CO2 gas adsorption (ca. 6-7 CO2 molecules per macrocycle) into very narrow cavities (narrowest part <2 angstrom), accompanied by the expansion of the cavities. The BF4- salt demonstrated selective uptake of CO2 gas in preference to CH4 and N-2 gases.
