Synthesis of gold and silver nanoparticles functionalized with organic dithiols
In this work commercially available bifunctional organic dithiols, 4,4?-dithiol-biphenyl (BI), 4,4?-dithiolterphenyl (TR) and the on purpose prepared precursor of 4,4?-dithiol-trans-stilbene (ST), have been used for the stabilization of gold and silver nanoparticles (AuNPs and AgNPs). The bifunctional thiols have been chosen with different conjugation length, to prepare interconnected system of nanoparticles in order to achieve a tuning of their optical properties.
