Self-Assemblies of Single-Walled Carbon Nanotubes through Tunable Tethering of Pyrenes by Dextrin for Rapidly Chiral Sensing

Figure 7

Schematic illustration of the principle of chiral selective sensing. Dispersion of SWNTs and fluorescence quenching of pyrene moieties (step i); fluorescence recovery of pyrene moieties through hydrophobic inclusion by CDs (step ii); chiral selective fluorescence quenching through competitive occupation of CD cavities by enantiomers (step iii).
