Tetracoordinated copper(I) complexes featuring aggregationinduced emission characteristics for sensitive detection of mercury ions

Key Points

• This research aims to create tetracoordinated copper(I) complexes for the sensitive detection of mercury ions.
• Synthesis of eight copper(I) complexes using diimine ligands and diphosphine ligands.
• Characterization of the emission properties of complexes Cu1–Cu8.
• Copper(I) complexes exhibited a range of green to red emissions.
• The complexes were evaluated for their sensitivity to mercury ion detection.
