A fluorescent cyclodextrin/carbon nanotube assembly was easily constructed through the non‐covalent attachment of adamantanylpyrene on carbon nanotube and the following association of cyclodextrin derivative bearing fluorescent substituent, and its structure was fully characterized by UV/Vis/NIR spectroscopy, Raman spectroscopy, X‐ray photoelectron spectroscopy, transmission electron microscopy and atomic force microscopy. Fluorescence spectroscopic and fluorescence microscopic studies showed that the resultant non‐covalently functionalized fluorescent nanotube could be used as a highly selective fluorescent probe for Zn 2+ in both water and living cells. Without carbon nanotube, the fluorescence probe was unable to enter the cell but only anchored on the cell membrane. This approach will overcome the disadvantage of many spectral sensors that are unable to enter living cells and greatly improve the application of naotube‐related supramolecular architecture in nanoscience and technology.
