Fluorescent Dendron–Cyclodextrin Nanotubes with Surface Peptide Spacer as a Recyclable Sensory Platform

Nanotube sensory platform: Dendron-cyclodextrin nanotubes with a surface coumarin unit attached by a GH dipeptide spacer were constructed by a combination of molecular recognition and self-assembly. These unique fluorescent nanotubes can serve as a recyclable metal ion sensory platform with high selectivity and sensitivity (see scheme).
