Application

HDT can be used to functionalize molybdenum disulphide (MoS2), which can be used as a two dimensional transition metal dichalcogenide (TMD) in electronics and optoelectronic devices. It forms a SAM on gallium arsenic (GaAs) doped cadmium sulfide (CdS) quantum dots (QDs), which can be used for biosensors and solar applications. It can also be used to immobilize gold nanoparticles (AuNPs) for potential usage in biomedical and bioanalytical applications.

General description

1,6-Hexanedithiol (HDT) is a long chained bi-functional alkanethiol with 6 carbon atoms structured in a zig-zag pattern, which forms a tetrahedral configuration. It is mainly used as a self-assembled monolayer (SAM) as it functionalizes various surfaces and immobilizes a variety of nanomaterials.
