Abstract

Complex formations in C₆₀ solutions and the reverse saturable absorption (RSA) properties have previously been observed. In a wide survey of solvents conducted in our laboratory, several solvents exhibited complexing behavior with C₆₀ when analyzed with UV-Vis and fluorescence spectroscopy. We have studied the formation of complexes in C₆₀/toluene solutions when benzonitrile, N-methyl-pyrrolidinone, and triphenylamine, and diethylaniline were added. Formation of the complexes was followed with UV-Vis spectroscopy. Several plots of the complexes were done to determine the equilibrium constant and the change in molar extinction coefficient in each system. We report the behavior of the reverse saturable absorption (RSA) properties as a function of complexing agent and concentration.
