Ruthenium polypyridyl phototriggers: from beginnings to perspectives

“…Density functional theory calculations of some Ru-bpy complexes show that the observed MLCT band is in fact the overlap of several transitions [11,23,27] and several different excited states, with somewhat different energies, can be populated. As the distribution of the populated excited states depends on the irradiation energy, it is not surprising that some complexes also exhibit a dependency of the activation energy E a on the irradiation wavelength.…”

Materials characterization by synchrotron x-ray microprobes and nanoprobes

“…For solid samples, the use of rotating and/or fast translating sample holders (supported by smart acquisition protocols) will allow one to change the sampling point before the maximum dose is reached. For liquid samples liquid jet setups (Salassa et al, 2010) are effective in reducing the dose per molecule. (iii) The sample environment should be optimized to maximize the heat exchange between the sample and the environment (Wallander and Wallentin, 2017); this includes the use of cryostats, high-heat-conducing sample holders, and a He atmosphere whenever possible.…”

Photoactivatable metal complexes: from theory to applications in biotechnology and medicine

“…TR-WAXS can detect the release of a pyridine ligand and the coordination of a solvent molecule on a faster time scale than 800 ns of laser excitation. This ultrafast dissociation of pyridine (from a Ru II complex which is highly inert in the ground state) appears to involve 3 MLCT or 3 MC states which decay on time scales of 100 ps to 5 ns, the former of which involves elongation and weakening of the Ru–N(py) bond [13]. …”
