<strong>Synthesis of tailored Aromatic quaternized Chitosan probes as switchable redox devices </strong>

Abstract

Involved in several physiological processes, redox behaviour has recently emerged as a promise research target requiring the design of compounds to be applied as sensor in a wide working window. In this communication, the synthesis of new quaternized pyridinium-chitosan derivatives by reaction of the biopolymer with electronically tuneable 2,4,6-triarylpyrylium tetrafluoroborates in mild conditions, and their characterization are described.
