Controllable Charge-Transfer Mechanism at Push–Pull Porphyrin/Nanocarbon Interfaces

Push–pull porphyrins are made of an electron donor (D), an electron acceptor (A), and a conjugated bridge connecting the D and A units. The tunability of their highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) gap can modulate their inter- and intramolecular charge-transfer (CT) and charge-separation (CS) characteristics and their reaction mechanism. Here, ultrafast charge transfer at the interfaces between...
