An aryl-triazole foldamer containing a 1,8-naphthalimide fluorescent motif for monitoring and enhancing the anion-induced folding

Abstract

A novel aryl-triazole foldamer incorporating a 1,8-naphthalimide motif was designed and synthesized. ¹H NMR, UV-vis and fluorescence spectroscopic titration experiments with halide anions (Cl⁻, Br⁻, I⁻) demonstrated that the π–π stacking interaction of 1,8-naphthalimide building blocks could largely enhance the folding and anion binding of the foldamer.
