The measurement of the electronic spectrum of triple-decker phthalocyanine trimer in solution showing the existence of lowlying excited states in the near-IR region is reported. The spectroscopic measurement in solution was made possible by using a newly synthesized trimer ( [ (Pc)Lu (CRPc)Lu(Pc) ]:

A recent reanalysis by Mikhelashvili and Mikhaeli of the effect of the spontaneous decay of the donor on the kinetics of Fiirster's electronic energy transfer is discussed critically. It is shown that their treatment is incorrect.
In our recent Letter we discussed the role of donor excitation natural decay in the charge and electron energy transfer processes. We turn our attention to the fact that, for the small lifetime of the donor's excited state, the existing theories of charge and electron energy transfer give asymptotic
