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 (N₂ , Ar, and CO₂ ) 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.

Keywords: dynamic response; interpenetration; metal-organic framework; nitroaromatic explosives detector.
