Porous cobalt(ii)-imidazolate supramolecular isomeric frameworks with selective gas sorption property

Abstract

Two porous supramolecular isomeric frameworks show unique sorption properties, one with temperature dependent stepwise and hysteretic selective sorption of CO(2) while the other one shows gas uptake capacity for CO(2), N(2), H(2) and CH(4) at low temperature and selective sorption of CO(2) over N(2) around room temperature.
