Single crystal X-ray-structurally characterized Mo( vi ) complexes of thiophene-appended amide–imine conjugates for optical recognition of calcon and 2-aminobutyric acid

Key Points

• The aim is to characterize Mo complexes with thiophene-based ligands for sensing applications.
• Characterized Mo vi complexes (M1, M2) using single crystal X-ray analysis.
• Utilized thiophene-based amide–imine ligands (L1, L2) in a fluorescence detection protocol.
• Conducted experiments in DMSO/H2O for optical recognition of target compounds.
• Achieved turn-on fluorescence indicating successful ligand displacement.
• Detected calcon and 2-aminobutyric acid at nanomolar concentrations.
• Demonstrated efficacy of the Mo complex as a sensor in aqueous environments.
