Perovskite-Structured PbTiO₃ Thin Films Grown from a Single-Source Precursor

Perovskite-structured lead titanate thin films have been grown on FTO-coated glass substrates from a single-source heterometallic molecular complex, [PbTi­(μ₂-O₂CCF₃)₄(THF)₃(μ₃-O)]₂ (<b>1</b>), which was isolated in quantitative yield from the reaction of tetraacetatolead­(IV), tetrabutoxytitanium­(IV), and trifluoroacetic acid from a tetrahydrofuran solution. Complex <b>1</b> has been characterized by physicochemical methods such as melting point, microanalysis, FTIR, ¹H and ¹⁹F NMR, thermal analysis, and single-crystal X-ray diffraction (XRD) analysis. Thin films of lead titanate having spherical particles of various sizes have been grown from <b>1</b> by aerosol-assisted chemical vapor deposition at 550 °C. The thin films have been characterized by powder XRD, scanning electron microscopy, and energy-dispersive X-ray analysis. An optical band gap of 3.69 eV has been estimated by UV–visible spectrophotometry
