Abstract
  • The synthesis and photophysical properties of a novel metallonucleoside, 5-[Ru(bpy)2(4-m-4‘-pa-bpy)]2+-2‘-deoxyuridine are reported. Spectroscopic studies show that the long-lived 3MLCT excited state is localized on the uridine-modified bipyridine.
  • The synthesis and photophysical properties of a novel ruthenium-modified nucleoside are reported. The key syntheticstep to 5-[Ru(bpy)2(4-m-4‘-pa-bpy)]2+-2‘-deoxyuridine involves the Pd(0)-catalyzed cross-coupling of a propargylamine-derivatized Ru(bpy)32+ and 3‘,5‘-dibenzoyloxy-2‘-deoxy-5-iodouridine. The long-lived 3MLCT excitedstate (1300 ns) of 5-[Ru(bpy)2(4-m-4‘-pa-bpy)]2+-2‘-deoxyuridine has an emission maximum centered at 640 nm.Step-scan Fourier transform infrared (S2FTIR) time-resolved spectroscopy reveals the excited-state electron to belocalized on the modified bipyridine with the excited-state dipole oriented toward the 2‘-deoxyuridine.
