    Photoinduced electron-transfer and magnetic field effects in clusters of C60 derivative (C60N+)- methylphenothiazine (MePH) system were investigated. Clusters of C60N+ were prepared by solving in THF-H2 O mixed solvent. Diameters of the clusters were estimated to be ca. 100 nm by using of dynamic light scattering and AFM measurements. Transient absorption spectra of the clusters of C60N+-MePH system following laser excitation at 355 nm indicate that photoinduced intermolecular electron-transfer from the triplet excited state of phenothiazine (PH) to C60 cluster occur. The yield of the escaped radical of PH increased with increase of magnetic field. The magnetic field effects suggest the generation of triplet radical pair.
