摘要：

Photoexcitation dynamics of a pyrene-C-60 dyad molecule has been investigated. From the excitation spectrum and fluorescence lifetime measurements, effective energy transfer processes from the singlet excited pyrene-moiety were confirmed both in polar and nonpolar solvents. The transient absorption suggested that the triplet excited C-60 was generated effectively upon excitation of the pyrene-moiety via the singlet energy transfer and the intersystem crossing process.
