Molecular precursor compounds, processes and compositions for making Zn-Group 13 mixed oxide materials including IZO, GZO, AZO and BZO, by providing inks comprising a molecular precursor compound having the formula MZn(OROR), and printing or depositing the inks on a substrate. The printed or deposited ink films can be treated to convert the molecular precursor compounds to a material.

Molecular precursor compounds for zinc-group 13 mixed oxide materials

A monomer is added to a solvent containing metal salt and porous support materials and the solvent is stirred for a period of time to distribute and fix the metal in the pores of the support materials. The solids that are dispersed in the solvent are then separated from the liquid, dried and calcined to form heterogeneous catalysts. The monomer that is added is of a type that can be polymerized in the solvent to form oligomers or polymers, or both. When forming heterogeneous catalysts containing platinum, acrylic acid is selected as the preferred monomer.
