A Europium ion post-functionalized indium metal-organic framework hybrid system for fluorescence detection of aromatics.

A Eu3+-functionalized In-MOF (In(OH)bpydc, bpydc = 2,2'-bipyridine-5,5'-dicarboxylate) hybrid system (In-MOF-Eu) with dual-emission is investigated for fluorescence sensing of benzene homologues (BTEX) in both vapor and liquid phases. A fluorescence test paper and a 2D-decoded map were designed to provide the potential for the convenient distinction of BTEX.
