Polarized Micropores in a Novel 3D Metal–Organic Framework for Selective Adsorption Properties

A novel 3D porous metal–organic framework with 1D polarized channels was synthesized, and its adsorption properties for gas separation and chemical sensing were studied. The framework shows a preferential adsorption of CO<sub>2</sub> over N<sub>2</sub> with a selectivity of 22:1. It also exhibits a very good sensitivity to water with respect to most of the organic solvents in view of chemical sensing applications.
