Self-Assembled Nanotubes Based on Chiral H₈-BINOL Modified with 1,2,3-Triazole to Recognize Bi³⁺ Efficiently by ICT Mechanism.

ABSTRACT: A novel fluorescent "off" probe R-β-D-1 containing a 1,2,3-triazole moiety was obtained by the Click reaction with azidoglucose using H₈-BINOL as a substrate, and the structure was characterized by ¹H NMR and ¹³C NMR and ESI-MS analysis. The fluorescence properties of R-β-D-1 in methanol were investigated, and it was found that R-β-D-1 could be selectively fluorescently quenched by Bi³⁺ in the recognition of 19 metal ions and basic cations. The recognition process of Bi³⁺ by R-β-D-1 was also investigated by fluorescence spectroscopy, SEM, AFM, etc. The complex pattern of R-β-D-1 with Bi³⁺ was determined by Job's curve as 1 + 1, and the binding constant K
