Reduction of Eu3+ to Eu2+ by an intense femtosecond laser pulse in solution

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.

PAMAM dendrimers functionalized with ruthenium nitrosyl as nitric oxide carriers Metallodendrimers Special Issue

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.
