rotation of the two naphthalene rings, binaphthyl derivatives are ideal candidates to be used as nonplanar spacers between electroactive units in the search for materials with enhanced dimensionality. The electronic absorption spectra of dimers in which the electroactive unit is in conjugation with the naphthalene fragment reveal the presence of intramolecularphotoinducedelectron-transfer process from

The first enantiomerically pure and soluble C(60) dimers have been synthesized from suitably functionalized 1,1'-binaphthyl derivatives by 1,3-dipolar cycloaddition of the respective in situ generated diazo compounds to C(60). These systems exhibit optical and electrochemical activity.
