ZnII-cyclen as a supramolecular probe for tagging thymidine nucleosides on carbon nanotubes Article uri icon

abstract

  • 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 ZnII-cyclen complex as a multidentate ligand for recognizing thymidine-derived multiwalled carbon nanotube derivatives (Td-MWCNTs). The effectiveness of the ZnII-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 ZnII-cyclen complex, allowing an accurate estimation of the Td moieties present on the CNTs surface. The ZnII-cyclen macrocycle is revealed to be an efficient and selective molecular probe for tagging thymidine (Td) nucleoside functionalities covalently linked to multiwalled carbon nanotubes (MWCNTs).
