Gold nanoparticles (GNPs) composited with controlled geometrical, optical, and surface chemical properties are the subject of intensive studies and GNPs/polymer composites have attracted increasing scientific interests because of their unique electronic, optical properties and potential applications<sup>[1]</sup>. In this paper, a series of pyrene-based discotic organic molecules were synthesized and the molecular structures were proved by <sup>1</sup>HNMR, FT-IR and TOF-MS spectra. GNPs decorated by pyrene-based compounds were obtained through Brust-Schiffrin method. DLS and TEM showed that the diameters of the nanoparticles were 3-5 nm and the photoelectrical properties of these composites were fully characterized by UV-Vis, PL spectra and CV curves. In addition, by solvent-exchange co-self-assembly of pyrene derivative composited with these functionalized nanoparticles, the different arrangements of gold nanoparticles were observed.
