Abstract:
Here we report enhanced CO2 molecular recognition ability by incorporating insertion reaction into a metal porphyrin complex in a metal-organic framework (MOF). PCN-222(Cu)-INA was synthesized by the reaction of PCN-222(Cu) [Zr6O8(H2O)8(Cu-TCPP)2], where Cu-TCPP = Cu(II) tetrakis(4-carboxyphenyl)porphyrin, and isonicotinic acid (INA). PCN-222(Cu)-INA exhibited a 1.5 times larger CO2 adsorption amount than PCN-222(Cu) at 298 K and 1 bar. The mechanism involving insertion reaction of CO2 into Cu–N bonds enhanced the adsorption, which was revealed by in situ IR spectroscopy and theoretical calculations.
