Nitroaromatic-explosives (NEs) not only threaten global security but are also recognized as a highly toxic pollutant. Metal–organic framework Zn-Ms (Zn-M1, Zn-M2) were synthesized in this study via the coordination-driven self-assembly of Zn ions and carbazole-based ligand L containing an aldehyde group. They inherited excellent fluorescence performance could work fluorescent sensor for detecting picric acid (PA) at low concentrations. showed emission 450 nm exhibited higher quenching efficiency toward PA than other related NEs. The results suggest that response might be attributed to inner filter effect (IFE); Förster resonance energy transfer (FRET); possibly, photo-induced electron (PET). In addition, critical role group recognition site was corroborated using post-modification strategy.
