AbstractSelf-assembled monolayer (SAM) of oxovanadium phthalocyanine (VOPc), an organic semiconductor compound. was prepared at room temperature on a highly oriented pyrolytic graphite (HOPG) substrate by immersing the substrate in a 1,2-dichloroethane (C2H4Cl2) colloidal solution containing both VOPc nanoparticles (2-20 nm) and dissolved VOPc molecules (ca 10(-3) g.L-1) The VOPc nanoparticles further assembled on the VOPc SAM The nanoparticle-assembling in the experimental conditions exhibited a high size-selectivity to VOPc nanoparncles of (4.60 +/- 0.47) nm with a standard deviation of 10% As revealed by scanning tunneling microscopy (STM) measurements, with increasing VOPc concentration of the colloidal solution from 2 5 x 10(-2) to 2 5 x 10(-1) g . L-1. the amount of VOPc nanoparticles assembled on the molecular layer increased gradually, and a dense VOPc nanoparticle monolayer formed in the end The found assembly structures and method are promising for the development of photoelectric or electric functional systems
