“…Since water generation by esterification of phosphonic acid (as in the first experiment) is relatively slow, water was deliberately added. Methacrylic acid was added anticipating an oxo cluster with a mixed ligand sphere as had been the case for analogous reactions with Ti(OR) 4 [ 15 , 17 ]. No mixed ligand cluster was obtained, however, in the reaction of Zr(O i Pr) 4 .…”

The clusters Ti5O(OiPr)11(OMc)(O3PR)3 (OMc = methacrylate; R = Et, CH2CH2CH2Br) and Ti10(OiPr)16(OMc)4(O3PCH2CH=CH2)10 were obtained when Ti(OiPr)4 was reacted with the corresponding bis(trimethylsilyl) phosphonate and methacrylic acid. Oxo clusters of the composition Ti6O4(OiPr)10(OMc)2(O3PR)2, with a variety of groups R (Et, Ph, CH=CH2, CH2Ph, CH2CH=CH2, CH2CH2CH2Br, CH2CH2CN, CH2C(O)Me, CH2CH2OC(O)C(Me)=CH2), were formed instead, when a stoichiometric amount of water was added to the reaction mixture.Graphical abstract

Organotitanias: a versatile approach for band gap reduction in titania based materials

et al. 2014

The reduction of the band gap of titania is critically important to fully utilize its photocatalytic properties.Two main strategies, i.e. doping and partial reduction of Ti(IV), are the main alternatives available to date.Herein, we report a new synthesis strategy based on one-pot co-condensation of in situ prepared polymetallic titanium-alkoxide complexes with titanium tetrabutoxide. Using this direct reaction, it is possible to introduce organic compounds in the anatase phase, causing site distortions in the crystalline structure of the network. By using this strategy, a yellow and a black titania have been produced, with the latter showing a remarkable photocatalytic activity under visible-light.
