| Popis: | Synthesis and spectroscopic investigation of trifluoroethoxy-coated phthalocyanine–fullerene dyad 2 has been described. While nonfluorinated phthalocyanine–fullerene dyad 1 showed an efficient property of intramolecular photoinduced electron transfer, dyad 2 , regardless of its covalently linked dyad system, appears not to show any electronic communication between fullerene and phthalocyanine. This observation is presumably due to the strong electron withdrawing nature of 12 trifluoroethoxy groups; fluorine leads phthalocyanine to become an acceptor whose electronic accepting property is equivalent to that of fullerene. This is a unique example that fluorine can terminate electronic communication in the covalently fullerene–phthalocyanine dyad system. |
