The molecular structure of the ClU\u2282DMP5A complex predicted from the present DFT calculations reveals that the ClU guest is completely encapsulated within the cavity of DMP5A. The ClU\u2282DMP5A complex is stabilized by C\u2013H\u00b7\u00b7\u00b7\n                    <jats:italic>\u03c0<\/jats:italic>\n                    interactions between the methoxy protons of DMP5A and the aromatic rings of ClU, together with displaced\n                    <jats:italic>\u03c0<\/jats:italic>\n                    \u2013\n                    <jats:italic>\u03c0<\/jats:italic>\n                    interactions, visualized as green sheet\u2010like regions in noncovalent interaction\u2013reduced density gradient analysis. On the other hand, the pyridine ring of ClPU interacts primarily with the methoxy substituents of DMP5A. The calculated interaction energy of ClU\u2282DMP5A (\u2212133.2\u2009kJ\u2009mol\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) is \u22482.9 times greater than that of ClPU\u2282DMP5A, indicating significantly stronger binding.

Cyclic voltammetry further demonstrates donor\u2013acceptor Lewis\u2010type interactions, with the fully encapsulated ClU\u2282DMP5A complex exhibiting a two\u2010electron transfer process,
