Highly Selective Sorption and Luminescent Sensing of Small Molecules Demonstrated in a Multifunctional Lanthanide Microporous Metal–Organic Framework Containing 1D Honeycomb‐Type Channels

A rare, robust microporous lanthanide metal-organic framework with 1D honeycomb-type channels is presented. Excellent adsorption capabilities for N(2), H(2), and CO(2) and significant selective sorption of CO(2) over N(2) and CH(4) 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.
