Europium 3+ ions in methanol were found to be reduced to the corresponding 2+ ions upon irradiation with intense femtosecond laser pulses. The excitation wavelength of 800 nm was nonresonant with their electronic transitions of Eu3+. It is notable that femtosecond white-light laser was generated when the reactions occurred. The mechanisms can be explained in terms of solvated electron formation followed by the reduction. The electron ejection in a focused beam in solution has been known to be accompanied by white-light laser.

The functionalization of three generations of polyamidoamine (PAMAM G0, G2 and G3) dendrimers with the NO-donor trans-[Ru(NO)(NH3) 4(ina)](BF4)3 (ina = isonicotinic acid) is reported. PAMAMs were modified through a peptide-type bond between the carboxyl group of the ina ligand and the dendrimer superficial amines. Compounds were characterized by FT-IR, UV-Vis, CV, DPV, 1H NMR, ICP-OES, and the structure of the complextrans-[Ru(NO)(NH3)4(ina)](BF 4)(SiF6)·H2O was determined by single crystal X-Ray analysis. The experimental data indicated the immobilization of 4, ~8 and ~27 nitrosyl complexes on the G0, G2 and G3 dendrimer's surface, respectively, which corresponds to ~1.0-1.43 μmol NO per mg of dendrimer. FT-IR, UV-Vis and electrochemical assays suggest that the functionalization of PAMAM did not alter the coordination sphere of the ruthenium nitrosyl complex neither the formal reduction potential of Ru IINO+/RuIINO0 couple regarding to the complex not attached to PAMAM. The NO release in these compounds, through light irradiation (λ = 355 nm) and one-electron reduction (Eu 2+), was investigated.
