In this report we examine the photophysical properties of two novel C-60 derivatives. These compounds consist of a ring-opened C-60 derivative (2) and its dihydro precursor (1), both of which include an orifice. The groundstate absorption spectra and the triplet-triplet absorption spectra were recorded for both derivatives. Extinction coefficients for the ground-state absorption (epsilon) and the triplet excited state (Delta epsilon(T-T)) were calculated. The derivatives have triplet energies (ET) lower than that of C-60, and the tripler quantum yields (phi(tau)) are somewhat lower than that of C-60 These compounds remain good photosensitizers for the formation of singlet oxygen, with high quantum yields (phi(Delta)). Thus, in many respects the photophysics of these buckyballs with an orifice still resemble pristine fullerenes.
