Abstract

C₆₀ dissolved in organic solvents is known to exhibit important nonlinear optical response leading to strong optical limiting action. However its solubility is very poor in most of the organic solvents and practically negligible in water. The fullerene molecules are indeed very hydrophobic compounds with a great tendency even in organic solvents to form aggregates. Among the main routes explored to modify their solubility and properties and in order to prevent aggregation, is their insertion in host matrices such as polymer, zeolites or complexing agents such as γ-cyclodextrins and calixarenes).
