  Ultrafast Ligand Exchange: Detection of a Pentacoordinate Ru(II) Intermediate and Product Formation

  摘要：

  The ultrafast kinetics of ligand exchange of cis-[Ru(bpy)(2)(CH3CN)(2)](2+) were measured in H2O and CH3CN. The formation of the (MLCT)-M-3 excited-state and a five-coordinate intermediate are observed in both solvents within 2 ps after excitation (310 nm, fwhm similar to 300fs). The (MLCT)-M-3 excited-state undergoes vibrational cooling (5-6 ps), then decays to regenerate the ground-state with a lifetime of similar to 50 ps. In CH3CN, ligand recombination takes place in 28 ps, while the formation of cis-[Ru(bpy)(2)(CH3CN)(H2O)](2+) in H2O takes place with tau = 77 ps.

  The first observation of photosubstitution products in electrospray mass spectra is reported. The solvent-coordinated Ru(II) complex ions created by photodissociation of Ru(2,2'-bipyrazine)(3)Cl-2, Ru(2,2'-bipyridine)(3)X(2) (X = Cl- and ClO4-), and the related complexes in acetonitrile solution were directly detected by on-line electrospray mass spectrometry. The mass spectra were well explained in terms of coordinating ability of counterions and solvent. Collision-induced dissociation in the gas phase was an important process particularly for interpretation of photoproducts such as weakly-bound solvent-coordinated complexes. It was found that the electrospray technique, combined with a flowing photoreaction cell, can potentially be used to identify photoproducts or intermediates.
