We present an extensive structural evaluation of hybrid architectures prepared by the “non-invasive” incorporation of gold nanoparticles (AuNPs) within an organic semiconductor matrix of diindenoperylene (DIP). The hybrid structures were characterized by advanced X-ray scattering techniques including grazing incidence small angle scattering (GISAXS), grazing incidence X-ray diffraction (GID), X-ray reflectivity (XRR) and complemented by atomic force microscopy (AFM) and transmission electron microscopy (TEM) measurements. We show that different strategies of incorporating the nanoparticles in the host matrix lead to drastically different structure and morphology. Particularly remarkable is the morphological change observed in the matrix of DIP as well as the AuNPs due to the influence of organic solvents. It is also demonstrated that AuNPs can be successfully used as tunable templates for the growth of the organic semiconductors with desired island sizes and distances.
