Abstract
The Langmuir monolayers of two crown-ether C60 derivatives with different crown size (18-crown-6, and 15-crown-5) were studied by surface spectrophotometry and Brewster angle microscopy. The surface pressure-area (π-A) isotherms of the C60 derivatives on pure water and different subphase ions were obtained. The limiting area of the isotherms depends on both the crown size and the presence of subphase ions. The larger crown size gave the larger limiting area of the isotherm. The addition of K•, Ba2• or NH4• to the subphase stabilized the monolayers and increased the limiting areas of the monolayer. Brewster angle microscopy shows different aggregation properties of crown-ether C60 derivative monolayers on pure water compared with those on K•, Ba2• or NH4• subphases.
