Covalent Bisfunctionalization of Two‐Dimensional Molybdenum Disulfide

Abstract

Abstract Covalent functionalization of two‐dimensional molybdenum disulfide (2D MoS 2 ) holds great promise in developing robust organic‐MoS 2 hybrid structures. Herein, for the first time, we demonstrate an approach to building up a bisfunctionalized MoS 2 hybrid structure through successively reacting activated MoS 2 with alkyl iodide and aryl diazonium salts. This approach can be utilized to modify both colloidal and substrate supported MoS 2 nanosheets. We have discovered that compared to the adducts formed through the reactions of MoS 2 with diazonium salts, those formed through the reactions of MoS 2 with alkyl iodides display higher reactivity towards further reactions with electrophiles. We are convinced that our systematic study on the formation and reactivity of covalently functionalized MoS 2 hybrids will provide some practical guidance on multi‐angle tailoring of the properties of 2D MoS 2 for various potential applications.
