Abstract A twin-axialhetero[5] pseudo rotaxane was constructed based on 1-hexyl-4,4′-bipyridinium guest 1 and cucurbit[8]uril (CB[8]) and α -cyclodextrin ( α -CD). In its structure, CB[8] included two bipyridinium units to realize the twin-axial mode, and the hexyl chain was threaded into the cavity of α -CD. The [5] pseudo rotaxane contains two types of macrocyclic hosts while the single axial and

A series of ionic complexes composed with ([Ni(qdt)2]2−) and alkyl substituted asymmetric viologen derivatives (AV+) as cations have been synthesized and characterized. A slight change in the length of the alkyl chain of AV+ alters the cation–anion packing and leads to different charge transport properties of these complexes. Here, we establish a structure–property relationship of Ni(qdt)2 complexes by structurally modifying the cations.
Interaction between cucurbit[6]uril (Q[6]) and the guest 1-hexyl-4-(4-pyridyl)pyridinium bromide (HV+) has been investigated by 1H NMR spectroscopy, mass spectrometry, isothermal titration calorimetry, and single-crystal X-ray diffraction analysis. Experimental results have shown that the host Q[6]) preferentially encapsulates the hexyl moiety of the 1-hexyl-4-(4-pyridyl)pyridinium bromide guest in
