Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC04421E, Feature ArticlePeter D. Matthews, Timothy C. King, Dominic S. Wright
Metal-doped polyoxotitanium cages can be regarded as molecular fragments of metal-doped TiO2 and can be used as structural models for the inclusion of metal ions into the TiO2 lattice. They are potential organically-soluble redox-catalysts for a range of organic transformations and have been shown to be useful single-source precursors for the deposition of metal-doped TiO2.
