Abstract

A series of two conjugates with La₂@C₈₀ and subphthalocyanine (SubPc) have been prepared and characterized by means of cyclic voltammetry, absorption, fluorescence, and femtosecond resolved transient absorption spectroscopy. The strong electron-donating character of La₂@C₈₀ is essential to power an intramolecular electron-transfer in the La₂@C₈₀–SubPc conjugates upon photoexcitation.
