CO2 selectivity of a 1D microporous adenine-based metal-organic framework synthesised in water

The coordination of adenine to Ni2+ forms a dimer unit which can be linked by 3,5-pyrazoledicarboxylic acid into chains which assemble under hydrothermal conditions via hydrogen bonding into a robust porous network. The material displays selectivity for CO2 over CH4 and an isosteric heat which increases with guest loading.
