Electrosynthesis and characterization of [Cu(Taab)(H2O)2](L)2 non-crystalline thin films
2011
Abstract Molecular-material thin films of diaqua tetrabenzo (b,f,j,n) {1,5,9,13} tetraazacyclohexadecine copper (II) bisanthraflavates and base organic molecules L have been electrodeposited on Corning 7059 glass slices, quartz substrates with tin oxide film and (100) single-crystalline silicon (c-Si) wafers. The surface morphology and structure of the deposited films were studied by atomic force microscopy (AFM), energy-dispersive spectrophotometry (EDS), ultraviolet–visible (UV–Vis) and Fourier-transform infrared (FT-IR) spectroscopies. The IR-spectra show that compounds obtained by chemical synthesis have the same absorption bands as the amorphous thin films obtained by electrosynthesis. The conductivities and the electrical-conduction mechanisms in the thin films were also investigated. Cubic nonlinear optical (NLO) characterizations of the film samples were performed with the Z-Scan technique, with some samples exhibiting remarkably high nonlinear activity.
