Two-step gas adsorption induced by the transmetallation in a two-dimensional metal–organic framework†
Abstract
Transmetallation or replacement of Zn2+ ions with Cu2+ ions in a two-dimensional metal–organic framework, Zn3(TCPB)2(H2O)2 (H3TCPB = 1,3,5-tri(4-carboxyphenoxy)benzene), gives rise to additional gas adsorption, where the additional adsorption amount linearly depends on the degree of the transmetallation.
