Fine-tuning the assemblies of carbon nanodots and porphyrins

Author affiliations

Abstract

We present charge-transfer assemblies of electron accepting, pressure-synthesized carbon nanodots (pCNDs) and an electron donating porphyrin. Amidine derivatization of the porphyrin allows for hydrogen bonding interactions with the carboxyl groups on the surface of pCNDs, which drive the formation of the assembly. Upon photoexcitation, this electron donor–acceptor supramolecular construct features ultrafast charge separation, and subsequent charge recombination in 27 ps.
