Photophysical behavior and selective Cu(II) and Hg(II) sensing of a Cyclen-Dansyl macrocyclic ligand with thiourea functionalization

Key Points

• Selective detection of Cu(II) and Hg(II) ions demonstrates the effectiveness of the macrocyclic ligand.
• The photophysical behavior provides key insights into the binding capacity of the ligand with transition metals.
• Assessment using thiourea functionalization proves advantageous for enhancing sensing properties of the ligand.
• The findings support the potential applicability of the ligand in environmental screening for heavy metal pollutants.
