Novel Soluble and Thermally Stable Perylene Dye with Two [60] Fullerene Units

A novel fullerene derivative in which perylene group is attached to two C60 through a pyrrolidine ring has been prepared and found to exhibit good solubility, high thermal stability and broad visible-light absorption with high coefficients, and photophysical studies shows that photo-induced energy transfer from the perylene moiety to C60.
