Highly Selective Sorption and Luminescent Sensing of Small Molecules Demonstrated in a Multifunctional Lanthanide Microporous MetalOrganic Framework Containing 1D Honeycomb-Type Channels

A rare, robust microporous lanthanide metalorganic framework with 1D honeycomb-type channels is presented. Excellent adsorption capabilities for N2, H2, and CO2 and significant selective sorption of CO2 over N2 and CH4 were observed. Moreover, the guest-dependent luminescent behavior of these lanthanide materials shows a potential use for the sensing of small-molecule pollutants such as benzene and acetone.
