A binuclear ruthenium(II) dimer (BiRD) bridged by an alkene linker was synthesized that was labile to reactive oxygen species generated by another photosensitizer. Compared to the monomeric Ru(II) complex, the BiRD had attenuated fluorescence and singlet oxygen production which could be restored by a longer-wavelength photosensitizer. This two-step amplification strategy demonstrates proof-of-principal for photosensitization chain-reactions. The Royal Society of Chemistry 2014.

This work demonstrated that a series of ultrabright fluorescent silica nanoparticles have been synthesized and designed via the reverse microemulsion method to encapsulate (2,2′-bipyridine)2-(5-aminophenanthroline) Ru bis(hexafluorophosphate) (Rubpy-phen). Transmission electron microscopy (TEM), scanning electron microscopy (SEM), dynamic light scattering (DLS), inductively coupled plasma (ICP) and fluorescence spectra were used to study the morphology and properties of the nanoparticles. By introducing ethanol into the reaction system, the obtained uniform fluorescent nanoparticles showed monodispersity and controllable size. With an increase of nanoparticle size (from 50-180 nm), the relative brightness of the nanoparticles was greatly improved from 534 to 86-972 by comparison with free dye molecules. Due to the protection of the silica matrix, the fluorescence of high concentration dye-doped silica nanoparticles (Rubpy-phen NPs) is not quenched, which results in higher fluorescence intensity and relative brightness. Moreover, the silica matrix can also protect Rubpy-phen from leakage. Due to the high brightness and biocompatibility, Rubpy-phen NPs have potential applications in the biological field.

An efficient photo-induced reduction of CO2 using magnetically separable Ru-CoPc@TiO2@SiO2@Fe3O4 as a heterogeneous catalyst in which CoPc and Ru(bpy)2phene complexes were attached to a solid support via covalent attachment under visible light is described. The as-synthesized catalyst was characterized by a series of techniques including FTIR, UV-Vis, XRD, SEM, TEM, etc. and subsequently tested for the photocatalytic reduction of carbon dioxide using triethylamine as a sacrificial donor and water as a reaction medium. The developed photocatalyst exhibited a significantly higher catalytic activity to give a methanol yield of 2570.78 μmol per g cat after 48 h. This journal is
