Helical Poly(quioxaline-2,3-diyl)-Based Poly(carboxylic acid)s as a Chiroptical Chemosensor for Detection and Quantification of Small Enantiomeric Imbalances of Chiral Amines in Water.

Achiral dynamic helical polymers, poly(quinoxaline-2,3-diyl)s ( and ) bearing achiral carboxylic acid side chains, i.e., carboxymethoxymethyl (in ) and carboxyethoxymethyl (in ), with different polymerization degrees were synthesized.
