One of the big challenges in the organic chemistry of functionalized carbon nanotubes (CNTs) is the characterization of their structure together with their physicochemical properties. In this work, we report the utilization of an acridine‐derived Zn II ‐cyclen complex as a multidentate ligand for recognizing thymidine‐derived multiwalled carbon nanotube derivatives (Td‐MWCNTs). The effectiveness of the Zn II ‐cyclen recognition has been confirmed through a combination of analytical techniques such as the Kaiser test, TGA‐MS, IR, X‐ray photoemission spectroscopy, TEM, UV/Vis absorption, and fluorescence spectroscopy. Taken together, the different characterization techniques have unambiguously shown the 1:1 recognition of the nucleoside by a Zn II ‐cyclen complex, allowing an accurate estimation of the Td moieties present on the CNTs surface.
