Title: Aluminum trihalide-neutral ligand ionic liquids and their use in aluminum deposition

Abstract

An ionic liquid composition comprising a complex of a trihalo aluminum (III) species with at least one organic uncharged ligand comprising a ring structure having at least three ring carbon atoms and at least one ring heteroatom selected from nitrogen and sulfur, wherein the complex is a liquid at a temperature of 100° C. or less. Methods of electroplating aluminum onto a metallic substrate using the above-described ionic liquid composition are also described.
