A Flexible Two‐Fold Interpenetrated Indium MOF Exhibiting Dynamic Response to Gas Adsorption and High‐Sensitivity Detection of Nitroaromatic Explosives

Abstract A flexible two‐fold interpenetrated indium metal‐organic framework InOF‐23 , featuring one‐dimensional micro‐sized channels decorated by exposed N groups, was successfully synthesized. Interestingly, InOF‐23 displays unique dynamic responses to different gases (N 2 , Ar, and CO 2 ) at low and room temperatures, which indicates that it can be a good candidate for gas adsorption and separation. Furthermore, the high efficiency detection for p ‐nitroaniline (pNA) makes InOF‐23 a potential chemosensor for nitroaromatic explosives.
