A stable water-soluble molecular precursor for the preparation of stoichiometric strontium titanate

Synthesis of Stoichiometric SrTiO3 and Its Carrier Doping from Air-Stable Bimetallic Complexes

“…In contrast, the solution processes are plausible for the synthesis of both bulk crystals and thin films with homogeneous composition . Because the conventional solution processes using independent Sr and Ti sources inhibit precise control of the stoichiometry, bimetallic complexes containing equal numbers of Sr and Ti atoms in a molecule have been surveyed as a single source for stoichiometric SrTiO 3 . − While alkoxide bimetallic complexes were unstable and easily formed impurities, catecholate and peroxo complexes were stable and applicable for the synthesis of SrTiO 3 . Especially, the Sr–Ti peroxo complex with an ethylenediaminetetraacetic acid (edta) ligand was synthesized under atmospheric conditions and was soluble in water, useful for solution processes.…”

Wheel-Like Icosanuclear Peroxotitanate—A Stable Water-Soluble Catalyst for Oxygen Transfer Reactions

“…Plenty of well-defined titanium peroxo complexes (TPCs) have been isolated, which include titanium salalen, − phthalocyanines, polyoxometalate, aminocarboxylate, − citrate, − and glycollate . These complexes contain no more than four peroxo groups; some of them have exhibited high catalytic performances for various oxidations with μ-η 2 :η 2 - − , or η 2 -peroxo coordination .…”
