Polycations XX: New Monodentate Cationic Ligands and Their Coordination with Ruthenium for the Construction of Complexes Expressing Enhanced Interaction with DNA
Figure 3
(a) Absorption spectra (200–650 nm) for ruthenium complexes of the type Ru(bpy)2L2 for L being monoalkylated 4,4′-bipyridyl monocations, noted as compounds 16, 17, 18, and 20. Relative maxima and their relative intensities for these spectra are provided in Table 1. (b) Absorption spectra (200–650 nm) for ruthenium complexes of the type Ru(bpy)2L2 for L being esters of nicotinic acid bearing dialkylated diazabicyclo[]octane units, noted as compounds 21 and 22. Relative maxima and their relative intensities for these spectra are provided in Table 1.
