4-(3-Phenylpropyl)pyridine is used in electrochemical processes for a novel system of microdroplets of PPP immobilized at graphite and in mesoporous ceramic electrodes, PPP has been used to investigate electrochemically driven mono-, di-, and tri-carboxylate anion transfer at the 4-(3-phenylpropyl)pyridine/aqueous electrolyte interface for a triple phase boundary system at graphite electrodes.
