  The [6,6]-ring bridged methanofullerenes 61,61-bis[4-tert-butylbenzoate]-1,2-dihydro-1,2-methanofullerene[60] (1), 61,61-bis[4-(tert-butyldiphenylsilyloxymethyl)phenyl]-1,2-dihydro-1,2-methanofullerene[60] (2), and 61-[(ethoxycarbonyl)methylcarboxylate]-1,2-dihydro-1,2-methanofullerene[60] (3) were synthesized by the Diederich method (3) or the Wudl method via tosylhydrazone salts (1 and 2). Groundstate absorption spectra of the methanofullerenes in toluene and cyclohexane solutions are presented and possible assignments discussed. The sharp, 430 nm transition is associated with the existence of less than 60 pi electrons, whereas a broad band peaking at 495 nm as well as weak features in the 700 nm region could be related to forbidden transitions of C-60. The allowed transitions of C,, in the UV region are modified relatively little in the methanofullerenes. Laser flash photolysis and pulse radiolysis techniques were used to obtain triplet-triplet absorption spectra between 400 and 1100 nm and determine photophysical properties. The three methanofullerenes have very similar T-T spectra, with a strong peak at 720 nm whose molar absorption coefficient is of the order of 14000 M(-1)cm(-1) somewhat lower than the 20200 M(-1)cm(-1) measured for the corresponding 750 nm band of C-60 Values near unity were determined for Phi(Delta) the quantum yield for O-1(2)((1) Delta(g)) production by energy transfer from the triplet state of the three methanofullerenes, implying that the quantum yield of triplet production of each is approximate to 1. The results indicate that it is possible for the spectroscopic and photophysical properties of methanofullerenes to vary little with the nature of the methano adduct and to undergo only slight modifications with respect to the corresponding properties of C-60. UP to now, this has been found valid only when the functionalization does not involve an electron donor, The biological photosensitization efficiencies of these methanofullerenes are therefore expected to be similar to those of C-60 but with their hydrophobicity and intracellular site delivery modulated by the nature of the methano-adduct.
