New polyads were obtained by covalently linking a coumarin dye to a fullerene (C-60) following two different strategies: 1,3-dipolar cycloaddition reaction of azomethine ylides or by cyclopropanation reaction. The new polyads are spectroscopically characterized and their fluorescence properties, including the observation of efficient singlet-singlet energy transfer, reported. (C) 2004 Elsevier Ltd.
