Abstract

Article history: In the present work the role of the thermal treatment on the reorganization of gold nanoparticles (AuNPs) Received 10 December 2015 functionalized with a -conjugated dithiol ligand, namely 9,9-didodecyl-2,7-bis-thiofluorene, is studied Received in revised form 1 February 2016 by grazing incidence X-ray diffraction technique. For a detailed investigation of the structural changes and Accepted 3 February 2016 reorganization occurring in the AuNPs network and of the monitoring of complex interactions between Available online 17 February 2016 nanoparticles, the line profiles are analyzed in out-of-plane and in-plane directions. The obtained data support the idea of the formation of a uniform network of nanoparticles that after annealing are extended Keywords: from hexagonal to cubic arrangement.
