Covalent Bisfunctionalization of Two-Dimensional Molybdenum Disulfide.

Area of Science:

• Materials Science
• Nanotechnology
• Chemistry

Background:

• Two-dimensional molybdenum disulfide (2D MoS₂) is a promising material for advanced applications.
• Covalent functionalization is key to developing robust organic-MoS₂ hybrid structures.

Purpose of the Study:

• To demonstrate a novel approach for bisfunctionalizing 2D MoS₂.
• To investigate the reactivity of different functionalization adducts.

Main Methods:

• Sequential reaction of activated 2D MoS₂ with alkyl iodide and aryl diazonium salts.
• Modification of both colloidal and substrate-supported MoS₂ nanosheets.

Main Results:

• Successfully synthesized bisfunctionalized MoS₂ hybrid structures.
• Alkyl iodide adducts exhibit higher reactivity towards electrophiles compared to diazonium salt adducts.

Conclusions:

• The developed method offers a versatile route for creating tailored 2D MoS₂-organic hybrids.
• This study provides guidance for multi-angle property tuning of 2D MoS₂ for diverse applications.
