Formation of porphyrin donor-acceptor complexes via an amidinium-carboxylate salt bridge

Porphyrins have been modified with an amidine functional group and they have been shown to bind carboxylic acids to form a amidinium-carboxylate salt bridge. These systems offer a new model to probe the mechanism of proton-coupled electron transfer (PCET).
