NOVELTY - Complex comprises one or more carboranes bound to a graphene. The carborane is a metallacarborane. USE - Complex used as composition in device (all claimed). ADVANTAGE - The complex has improved approach to synthesizing and utilising graphene and in particular functionalised forms. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for following: (1) a method for producing a complex comprises one or more metallacarboranes covalently bound to a graphene, which involves reacting a graphene with a carborane in a dehydrogenation and/or deboronation reaction to obtain a graphene covalently bound with one or more carboranes;isolating graphene bound carborane;contacting the material with a strong base and a metal halide; and (2) a composition, which comprised a complex and one or more additives; and (3) a device, which comprises a surface on which a layer of a complex or a composition is printed.
