Light‐Controlled [3]Pseudorotaxane Based on Tetrasulfonated 1,5‐Dinaphtho‐32‐Crown‐8 and α‐Cyclodextrin

Abstract: The synthesis of advanced molecular machines represents one of the significant topics in supramolecular chemistry. In this work, a multicomponent molecular machine was successfully constructed by the inclusion complexation of azophenyl derivative bearing pyridinium terminals (G1) with α-cyclodextrin (α-CD) and tetrasulfonated 1,5-dinaphtho-32-crown-8 (DNC) in water, which was comprehensively characterized

“…1 ), the system may reversely accept and release CDs in solution upon application of an appropriate stimulus. While CDs are known to be the host in almost all cases, reports on their use as guest are rare 26 . Therefore, the present system is a rare example where CDs behave as the guest in a host–guest molecular interaction.…”

“…For these reasons, CDs are widely used in the pharmaceutical and health care sectors for the delivery of active principles. The presence of several hydroxyl groups with different reactivities allows to functionalize the CD cone in a selective way and to modify the physicochemical properties of the final derivative for applications . Considering also the possibility to build complex supramolecular architectures, the applications of CDs nowadays span from the design of molecular machines to the development of nanovectors for cancer treatment and gene delivery. With specific reference to medical diagnostics, CDs are, for the same reasons, also promising candidates for the synthesis of advanced contrast agents for MRI. …”

“…Moreover, owing to their cone-shaped structure and chemical versatility, they can form inclusion complexes with several molecules and are widely used in the pharmaceutical and health sectors for the delivery of active principles . Accordingly, their applications nowadays span from the development of nanovectors for cancer treatment and for gene delivery to the development of contrast agents. Hence, the possibility to perform DNP on β-CD would allow to follow through in vivo molecular imaging the fate of the drug hosted by the CDs. In previous works, , we managed to raise 1 H and 13 C nuclear polarizations up to 10 and 7%, respectively.…”
