AbstractThe layer-by-layer growth of film structures consisting of sequential depositions of oppositely charged polymers and macrocycles (ring-shaped molecules) have been constructed using molecular self-assembly techniques. These self-assembled thin films were characterized with X-ray reflectometry, which yielded (1) the average electron density, (2) the average thicknesses, and (3) the roughness of the growth surface of the self-assembled multilayer of macrocycles and polymers. These observations suggest that inorganic-organic interactions play an important role during the initial stages of thin-film growth, but less so as the thin film becomes thicker. Optical absorption techniques were also used to characterize the self-assembled multilayers. Phorphyrin and phthalocyanine derivatives were chosen as the building blocks of the self-assembled multilayers because of their interesting optical properties.

AbstractPoly(γ-benzyl-L-glutamate) (PBLG) derivatized at its N-terminus with lipoic acid, a disulfide-containing moiety, self-assembles on gold from helicogenic solvents to give a thin film with the polypeptide α-helices orientation distribution different from the planar orientation in the unlabeled, physisorbed PBLG films (control) and Langmuir-Blodgett monolayers. The SA films were studied by angle-dependent XPS, reflection-absorption FTIR spectroscopy, and ellipsometry. The IR dichroic properties of the amide I and amide II bands were used to infer the orientational distribution of the helices in the self-assembled film and lead to two extreme pictures of the helix axis distribution function: (a) random (hemispherical distribution) and (b) perfect order with a tilt of 53° from the surface normal. Additional characterization is necessary to differentiate between these two distributions.

This article used PTCS to dispose the self-assembled substrate, and prepared the precursor by the ratio of AHFT / SN / BA = 1:1:3 and then immersed the functionalized substrate into the precursor supersaturated solution. With the colloidal particles absorption induced by SAMs, SrTiO3 thin film was prepared by the self-assembled monolayers with liquid phase deposition method. The effects of the time of UV radiation and the time of PTCS immersion on the substrate contact angle were studied and the time of UV radiation had an effect on the substrate functionalization after PTCS immersion. The results showed that the first UV radiation for 25 min, PTCS immersion for 7 min and the second UV radiation for 30 min were beneficial to the crystallization of SrTiO3. XRD and AFM were used to characterize the thin film physical phase and surface morphology at 600oCwith annealing and heat retaining for 2 hours. The results also showed that under the same condition, the SrTiO3 crystals on the thin film surface had the clear outline and the spherical crystals were distributed regularly and evenly.
