Area-selective monolayer deposition of iron(II) α-octabutoxyphthalocyanine complex on nano-patterned TiO2 thin films on a glass substrate

摘要: Abstract Iron(II) 1,4,8,11,15,18,22,25-octabutoxyphthalocyanine complex (Fe(OBu)8Pc) was synthesized and deposited on nano-cratered titanium dioxide thin films a glass substrate. The TiO2 had been selectively modified with bifunctional 2-aminoethyl dihydrogen phosphate, which binds to the surface from its phosphate group, but leaves substrate unmodified, creating hence nano-patterned amino-functionalized surface. n-Butyl amine used as model ligand examine ability of Fe(OBu)8Pc bind amino groups in solution state. According 1H nuclear magnetic resonance UV–Vis measurements, two separate can axial sites using coordination bonds. molecules form monolayer an when THF solvent deposition step. X-ray photoelectron spectroscopy scanning electron microscopy analysis results indicate that complexes lie parallel carrier replicating nanostructure while having free for sensing applications leaving floors craters available further functionalization.
