Abstract/Description: Controlled growth of the aromatic p-phenylene oligomer molecules of p-4P, p-5P, and p-6P adsorbed onto individual KBr(001), KCl(001), NaCl(001), and NaF(001) substrates, has been investigated primarily by x-ray diffraction (XRD) and to a lesser degree by atomic force microscopy (AFM). XRD analysis provides evidence that the temperature of the alkali halide substrate during deposition, substrate lattice constant, and molecular length affects the molecular orientations within these adsorbed ultrathin films. AFM images contribute independent evidence for a surface microstructure evolution that is consistent with the XRD results. An initial in-plane x-ray study suggests a possible explanation for the preferential orientation of p-6P crystallites, as observed in AFM images. This alignment is approximately along the [110] direction of the KCl(001) substrate. From this work, oriented films of the above mentioned p-phenylene oligomer molecules can therefore be grown with desired molecular orientations by careful selection of an appropriate combination of the above deposition parameters.
