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

{{output}}
Achiral dynamic helical polymers, poly(quinoxaline-2,3-diyl)s (P1 and P2) bearing achiral carboxylic acid side chains, i.e., carboxymethoxymethyl (in P1) and carboxyethoxymethyl (in P2), with different polymerization degrees were synthesized. They exhibited in... ...
