Abstract

Langmuir films have been prepared using pure C₆₀ and arachidic acid mixed with C₆₀ in the ratio of 1 : 1 and 4.2 : 1. Langmuir–Blodgett (LB) films were then deposited on a variety of substrates with Y-type deposition being observed. Films containing bilayers of arachidic acid alternating with both single and double monolayers of C₆₀ were prepared. The structure of the arachidic acid component in the mixed films was investigated by grazing-incidence FTIR spectroscopy and was shown to be similar to that in an LB film of pure arachidic acid. The absence of structural disruption in the presence of C₆₀ provides strong evidence for an ordered alternant arrangement of fullerenes and arachidic acid in the films.
