Abstract
[60]Fullerene has been shown to have a very high quenching effect on the fluorescence of anthracene at room temperature in n-hexane, n-heptane and carbontetrachloride medium. The possibility that the quenching is due to ground state electron donor–acceptor (EDA) complex formation between [60]fullerene and anthracene has been shown to be untanable in the concentration range used (∼10−5 mol dm−3 in both anthracene and C60). No exciplex formation under the present experimental conditions has been observed. In the non-quenching solvents n-hexane and n-heptane the Stern–Volmer constant follows the right trend with respect to change in solvent viscosity but in case of the quenching solvent CCl4, the trend is opposite.
