Rationally Designed Micropores within a Metal−Organic Framework for Selective Sorption of Gas Molecules

Abstract

A microporous metal-organic framework, MOF, Cu(FMA)(4,4'-Bpe)0.5 (3a, FMA = fumarate; 4,4'-Bpe = 4,4'-Bpe = trans-bis(4-pyridyl)ethylene) was rationally designed from a primitive cubic net whose pores are tuned by double framework interpenetration. With pore cavities of about 3.6 A, which are interconnected by pore windows of 2.0 x 3.2 A, 3a shows highly selective sorption behaviors of gas molecules.

Modeling adsorption equilibria of xylene isomers in a microporous metal–organic framework

“…Contrasting to zeolites, which have pores confined by tetrahedral oxide skeletons, the pores within MOFs can be systematically varied by the judicious choice of the metal-containing and/or organic ligands [19]. Due to their unusual features, MOFs are considered promising materials for gas storage, adsorption separations and catalysis [20][21][22][23][24][25][26][27][28][29][30][31][32].…”

“…S3, ESI †), although the peaks of UTSA-60a are slightly different from those of the as-synthesized UTSA-60 due to the flexible nature of double-bond spacers in the organic linker. 15 The permanent porosity was established by nitrogen sorption at 77 K. The N 2 sorption isotherm at 77 K exhibits a typical Type-I sorption behaviour, characteristic of a microporous material (Fig. S6, ESI †).…”
