Covalent functionalization of two-dimensional molybdenum disulfide (2D MoS ) holds great promise in developing robust organic-MoS hybrid structures. Herein, for the first time, we demonstrate an approach to building up a bisfunctionalized MoS hybrid structure through successively reacting activated MoS with alkyl iodide and aryl diazonium salts. This approach can be utilized to modify both colloidal and substrate supported MoS nanosheets. We have discovered that compared to the adducts formed through the reactions of MoS with diazonium salts, those formed through the reactions of MoS 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 hybrids will provide some practical guidance on multi-angle tailoring of the properties of 2D MoS for various potential applications.
二维二硫化钼(2D MoS₂)的共价功能化在开发坚固的有机 - MoS₂混合结构方面具有巨大潜力。在此,我们首次展示了一种通过使活化的MoS₂先后与烷基碘和芳基重氮盐反应来构建双功能化MoS₂混合结构的方法。该方法可用于修饰胶体和基底负载的MoS₂纳米片。我们发现,与通过MoS₂与重氮盐反应形成的加合物相比,通过MoS₂与烷基碘反应形成的加合物对与亲电试剂的进一步反应表现出更高的反应活性。我们相信,我们对共价功能化MoS₂杂化物的形成和反应活性的系统研究将为二维MoS₂各种潜在应用的性能多角度定制提供一些实用指导。
