Abstract
We study the adsorption behaviors of dodecahydroxylated-fullerene C 60 (OH) 12 at the air-water interface. With the hydrophilicity imposed by the 12 hydroxy groups randomly bounded on the C 60 cage, C 60 (OH) 12 can dissolve in water slightly. Surface pressure-area isotherms, Brewster angle microscopy, and neutron reflection results for the aqueous solutions of C 60 (OH) 12 provide consistent evidence of adsorbed C 60 (OH) 12 monolayers at the air-water interface. A Langmuir-Blodgett film of C 60 (OH) 12 , prepared from the sample solution with the vertical dipping method, is examined using atomic force microscopy.
