Tuning intramolecular electron and energy transfer processes in novel conjugates of La2@C80 and electron accepting subphthalocyanines
2015
Abstract
A series of two conjugates with La-2@C-80 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 La-2@C-80 is essential to power an intramolecular electron-transfer in the La-2@C-80-SubPc conjugates upon photoexcitation.
