Novel triarylamine-based aromatic polyamides bearing secondary amines: synthesis and redox potential inversion characteristics induced by pyridines

Abstract

Novel triarylamine-based aramids with secondary amine moieties are prepared and utilized as electrochemical detectors for pyridines. Their electrochemical behavior with different pyridines was investigated in order to demonstrate the ionic hydrogen bonding interaction of the secondary amine with the pyridines, resulting in obvious potential inversion which is also supported by in situ absorption measurements.
