STRUCTURE AND PHYSICAL-PROPERTIES OF LANGMUIR-BLODGETT-FILMS OF C60 WITH AMPHIPHILIC MATRIX MOLECULES

Langmuir-Blodgett (LB) films Of the fullerene (C60) were formed with a variety of matrices. The pure C60 formed a collapsed film at the air- water interface and the transferred film had an inhomogeneous surface. By mixing with icosanoic acid, the monolayers were transferred onto s ubstrates with good quality and the resultant LB films had a smooth su rface. The 1:1 mixture with dioctadecyldimethylammonium-ClO4 was depos ited as Z-type film onto substrates. The film is, however, composed of doughnut-shaped aggregates for a single-layered sample. Multilayered samples had undulations of ca. 100 nm. The absorption spectra of both of the mixed films were in good agreement with those of evaporated fil ms. The LB films with a long-alkyl gamma-cyclodextrin were also examin ed.
