摘要
Two novel homoleptic ruthenium (11) complexes containing asymmetric tridentate ligands, 2-(benzimidazole-2-yl)-1,10-phenanthroline (PHBI) and 2-(naphtho[2,3-d]imidazole-2-yl)-1,10-phenanthroline (PHNI) have been synthesized and characterized by elemental analysis, mass spectra, H-1 NMR, and electronic spectroscopy. The DNA-binding properties of the complexes have been investigated by spectroscopic methods and viscosity measurements. The results indicate that the two complexes interact with DNA via electrostatic interaction, and the mechanisms of DNA binding with the complexes have also been discussed. (C) 2004 Elsevier Inc.
