The synthesis of three novel pyrazolo[60]fullerene derivatives containing electron-withdrawing substituents has been described. High solubility in ordinary organic solvents was proved. Their electrochemical properties of pyrazolo-[60]fullerenes showed better electron affinity than pristine C 60 in the ground state. The nanosecond transient absorption spectra showed clear evidence for photoinduced electron transfer from TTF to the excited triplet state of the pyrazolo-[60]fullerenes, in which stronger electron-withdrawing substituents accelerate the rates of the photoinduced electron-transfer, indicating a high electron-acceptor ability of the excited triplet state of pyrazolo[60]fullerenes.
