Molecular panels for energy transduction in C60-based conjugates.

Light-harvesting C(60)-based dyads endowed with a truxene fluorophore unit have been synthesized. Their photophysical studies in solution reveal a singlet-singlet energy transfer deactivation mechanism that confirms the actuation of the latter as an efficient molecular panel for light absorption and energy transduction. Those processes strongly depend on the nature of the linker connecting both chromophores, such as C(60) and truxene, owing to the overlapping degree between their respective orbitals.
