Aerosol-assisted CVD of thioether-functionalised indium aminoalkoxides.

ABSTRACT: Thioether-functionalised indium aminoalcoholates have been used as single-source precursors in aerosol-assisted CVD processes. The obtained In2O3-x S x oxysulphide deposits show either a single indium sulphide phase for deposits with high sulphide content [>75% (S/(S + O)) for the t-butyl derivatives] or pronounced phase separation in indium oxide and indium sulphide for lower sulphide content [<62% (S/(S + O)) for the n-butyl derivatives]. In addition to thin films, polycrystalline 1D structures are obtained at slightly modified synthesis conditions. The materials are analysed by EDX, XRD, XPS, SEM, and TEM.

Synthesis and characterisation of thioether functionalised gallium and indium alkoxides.

This paper provides evidence of formerly unknown thioether coordination in metal alkoxides. The thioether functionalised alkanols serving as alcoholate ligands have been prepared by a generic route. The gallium and indium alkoxides provide the first evidence for sulphur coordination in the liquid and solid state in metal alkoxide derivatives. The presence of amines suppresses the coordination of thioether moieties leading to a well-known bonding mode in aminoalcoholates.
