摘要：

The excited-state properties of lutetium bis-phthalocyanine (LuPc2) in solution in three different redox states (LuPc2., LuPc2+ and LuPc2-) have been investigated. Upon excitation at either 354, 532 or 1064 nm, LuPc2. deactivates through a low-lying doublet excited state of charge transfer nature with a 60 ps lifetime. No evidence for charge hopping between the two phthalocyanine cycles of the dimer was observed. LuPc2+ and LuPc2- also have short-lived excited states (60 and 36 ps, respectively) suggesting a common deactivation process, possibly vibrational relaxation via low-lying charge transfer states.
