    We report the first instance of observing the phototriggered isomerization of dmso ligands on a bis sulfoxide complex, [Ru(bpy) 2 (dmso) 2 ], in the crystalline solid state. The solid-state UV-vis spectrum of the crystal demonstrates an increase in optical density around 550 nm after irradiation, which is consistent with the solution isomerization results. Digital images of the crystal before and after irradiation display a notable color change (pale orange to red) and cleavage occurs along planes, (1̄01) and (100), during irradiation. Single crystal X-ray diffraction data also confirms that isomerization is occurring throughout the lattice and a structure that contains a mix of the S , S and O , O / S , O isomer was attained from a crystal irradiated ex situ . In situ irradiation XRD studies reveal that the percentage of the O-bonded isomer increases as a function of 405 nm exposure time.

    Five bismuth-organic materials that exhibit fluorescence or phosphorescence and radioluminescence are reported, with the photophysical behavior dependent on both the identity of the outer sphere fluorophore and noncovalent interactions.

    Transient absorption data of [Fe II (tpy)(CN) 3 ] − reveals spectroscopic signatures indicative of 3 MLCT with a ∼10 ps kinetic component. These data are supported by DFT and TD-DFT calculations, which show that excited state ordering is responsive to the number of cyanide ligands on the complex.

    A series of Ru( ii )-terpyridine complexes containing electron-donating bidentate ligands are able to effectively photodissociate nitrile ligands using red light. A spectroscopic investigation of these complexes reveal that they follow anti-energy gap law behavior, providing further evidence that population of 3 LF excited states is not necessary for photoinduced nitrile dissociation.
