- Abstract
- Gold nanoparticles stabilized by two novel bifunctional fluorenyl thiols, generated in situ from 9,9-didodecyl-2,7-bis(acetylthio)fluorene (1) and 9,9-didodecyl-2,7-bis(acetylthiophenylethynyl)fluorene (2), exhibit bridged structures which self-assemble in parallel lines. The size, shape and structure of the AuNPs have been detd. by means of dynamic light scattering (DLS), SEM (FE-SEM), transmission electron microscopy (TEM) and XPS. AuNPs modified with fluorenyl thiol derivs. show diams. in the range of 3-7 nm. The linkage between the nanoparticles can be envisaged with the formation of dyads supported by TEM anal. and XPS measurements. Remarkably, investigation by SEM of the AuNP films revealed an ordered distribution of well-sepd. individual nanoparticles to form a 2D network. The formation of interconnected networks between AuNPs with different distances, depending on the nature of the thiol linkers (1) or (2), and the photoluminescence properties open perspectives for applications in optical devices and electronics.
