Tailoring open metal sites for selective capture of CO2 in isostructural metalloporphyrin porous organic networksElectronic supplementary information (ESI) available. See DOI: 10.1039/c5nr05696a

Porphyrin-based isostructural porous organic networks have been synthesized by varying the central metal atoms to cobalt, nickel and copper. Their selectivities for CO 2 capture over N 2 and Ar are found to be enhanced as the heats of adsorption for CO 2 are increased in the order of Co, Ni and Cu,...

Description
Summary:Porphyrin-based isostructural porous organic networks have been synthesized by varying the central metal atoms to cobalt, nickel and copper. Their selectivities for CO 2 capture over N 2 and Ar are found to be enhanced as the heats of adsorption for CO 2 are increased in the order of Co, Ni and Cu, while the pore structures are well maintained. CO 2 can be selectively captured over N 2 or Ar by tuning the metalloporphyrin building units of isostructural porous organic networks, giving a selectivity correlated with heat of adsorption via adsorbate-adsorbent interactions.
