Abstract:
We study the adsorption behaviors of
dodecahydroxylated-fullerene C60(OH)12 at the air-water
interface. With the hydrophilicity imposed by the 12
hydroxy groups randomly bounded on the C60 cage,
C60(OH)12 can dissolve in water slightly. Surface
pressure-area isotherms, Brewster angle microscopy, and
neutron reflection results for the aqueous solutions of
C60(OH)12 provide consistent evidence of adsorbed
C60(OH)12 monolayers at the air-water interface. A
Langmuir-Blodgett film of C60(OH)12, prepared from the
sample solution with the vertical dipping method, is
examined using atomic force microscopy.
