C60-oPPE-C6o—A Representative Example for Efficient Energy Transfer

1 C6o-oPPE-C60—A Representative Example for Efficient Energy Transfer 

In view of the molecular-wire properties of o%o-phenyleneethynylenes (oPEs), C6o-wire-C6o conjugates 3 have been investigated, where two C60s were attached

The lack of significant electronic interactions between the electroactive constituents in the ground state prompts to the excited state characteristics. This has been accomplished by various photophysical methods. A short summary of the results will be presented in this chapter to set the tone for the following energy transfer discussions. 

Within the context of the current systems, only the weak fluorescing features of C6o that are maximized at 710 nm should be mentioned explicitly. A representative emission spectrum is illustrated in Fig. 8.2a. Regarding, the phenylene-acetylene building blocks, the major features include strong visible light fluorescence with quantum yields close to unity. Similarly to the absorption maxima, the fluorescence
