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.

Methacrylic monomers with pyrylium salt derivatives are widely used to detect nucleophilic species. A new synthesis method has been used to obtain a pyrylium salt that is trisubstituted with phenyl groups at positions 2,4, and 6. The phenyl group of the 4-position has a metacrylate group in the para-position. The new synthesis method implies the esterification of 4-hydroxybenzaldehyde, using methacrylic anhydride. The formed compound react with acetophenone to form the pyrylium derivative. The yields of both reactions are greater than those previously reported in the literature.
