Preparation and characterization of Langmuir-Blodgett films of endohedral metallofullerene Gd@C_(82)

摘要

Monolayer Langmuir-Blodgett (LB) films of metallofullerene Gd@C_(82) mixed with stearic acid (Gd@C_(82)/SA) were deposited onto mica substrates from the air/water interface. The structural characteristics of these films were studied by atomic force microscopy (AFM) and contact angle (CA). The results showed that the metallofullerene Langmuir-Blodgett (LB) films with SA (Gd@C_(82)/SA) were easily fabricated by vertical dipping method compared to the pure metallofullerene film. When the molar ratio of SA:Gd@C_(82) was up to 4:1, the corresponding LB films exhibited a uniform and ordered layer structure.
