Abstract—The structure of fullerene C₆₀ Langmuir layers formed from a solution in cyclohexane has been
determined from their compression isotherms. The layer structure, in particular, the size of formed aggregates,
has been shown to depend on the initial surface concentration of fullerene. A quantitative model of the Lang-
muir layer has been proposed. Degrees of water surface coverage with fullerene (the initial one and that corre-
sponding to the onset of one-phase state formation), intermolecular distances of fullerene in aquaaggregates,
aggregation numbers, and distances between aquaaggregates have been found to play the role of the model
parameters. Constants characterizing the structure of a stable monolayer have been determined on the basis of
the formulated model.
