Abstract

A fluorescence “turn-on” phenomenon was observed in the β-aminoacrylate-based low-molecular-weight motif methyl-3-(propylamino)acrylate and its polymers in the presence of an acid, which catalyzes the formation of dihydropyridine derivatives. This unique feature could be applied in anti-counterfeiting patterns.
