DNA-interacting lanthanide complexes with a DOTA-derived dipyrido3,2-a;2',3'-cphenazine ligand for near-infrared luminescence

Key Points

• This research aims to explore the luminescent properties of DNA-interacting lanthanide complexes using a specific ligand.
• Used dipyrido[3,2-a:2',3'-c]phenazine (dppz) ligand for lanthanide sensitization.
• Tested lanthanide ions Nd3+, Er3+, and Yb3+ for near-infrared emission capabilities.
• Analyzed the interaction between the ligand and DNA for luminescence effectiveness.
• Confirmed that dppz effectively sensitizes lanthanide ions, enhancing near-infrared luminescence.
• Demonstrated significant interaction between the ligand and DNA structures observed in luminescent profiles.
