Langmuir-shäfer (horizontal lifting) construction and characterization of nanostructured assemblies of an amphiphilic fulleropyrrolidine and a water-soluble porphyrin (original) (raw)

2004

Abstract

Characterization of the thin films consisting of an amphiphilic fulleropyrrolidine and a novel water soluble porphyrin using Langmuir-ShA¤fer (LS) was investigated. The characterization of the LS films by UV-Vis spectroscopy revealed that the UV region was dominated by optical absorptions of the C60 subunits, while the porphyrin absorptions were very weak in this region. The use of polarized light suggested the existence of a preferential direction of macrocycle rings with an edge-on arrangement with respect to the substrate surface. The films deposited onto ITO substrates in which the floating films were transferred onto the ITO electrodes by the LS method at several surface pressures were also investigated.
