▎ 摘  要

A platinum complex bearing a N-heterocyclic carbene (NHC) ligand functionalised with a pyrene-tag is immobilised onto the surface of reduced graphene oxide (rGO). The hybrid material composed of an organometallic complex and a graphene derivative is ready available in a single-step process under mild reaction conditions. This methodology preserves the inherent properties of the active catalytic centre and the support. The platinum hybrid material is an efficient catalyst in hydrosilylation of alkynes and can be recycled and reused without significant loss of activity due to its high stability. Interestingly, the catalytic activity of the platinum complex is not affected by diffusion problems after immobilisation. The influence of graphene in hydrosilylation of alkynes is discussed in terms of activity and selectivity.
