Abstract
The invention is directed to making inorganic materials consisting of a metal and a group 16 element in the stoichiometric ratio of 2:3 from single source precursors having the same 2:3 metal to heteroatom stoichiometric ratio. In particular, the invention discloses a process for making aluminum oxide from single source precursors that have an aluminum to oxygen ratio of 2:3. The precursors are organoaluminum tetrametallic compounds containing organooxy bridging groups and organo terminal groups. As these compounds tend to be viscous liquids or oils, they can be applied to a substrate surface then pyrolyzed to eliminate the organic ligands and produce aluminum oxide in situ, without using gas phase deposition techniques.
