Resumen:
We report the synthesis and electron donor-acceptor features of a novel nano-hybrid, in which the light harvesting and electron donating properties of a meso-tetraarylporphyrin (TArP) are combined with the electron accepting features of Nitrogen-Doped Carbon Nanodots (NCNDs). In particular, in an ultrafast process (> 1012 s-1), visible light excitation transforms the strongly quenched porphyrin singlet excited states into 225 ps lived charge separated states. On the other hand, ultraviolet light excitation triggers a non- resolvable transduction of singlet excited state energy from the NCNDs to the porphyrins, followed by the same charge separation observed upon visible light excitation.
