“…Our results obtained previously [53] and in this investigation demonstrate the possibility of creating switchable systems with the redox-conversion of calixarene containing redox-active groups. In particular, the electro-switchable binding of tatraanions (SCA 4-and [Fe(CN) 6 ] 4-) with MVCA 8?…”

“…The investigated salts, including MVCA 8? Á8PF 6 -readily dissociate in polar media, as do the salts, which can be formed in the presence of the background electrolyte NaClO 4 [53]. Thus, 60 vol.% aqueous DMSO media makes it possible to operate with individual ions: [Fe(CN) 6 ] 4-, MV 2?…”

“…Thus, MV 2? undergoes two reversible reductions with the formation of a stable cation-radical MV ?Á and neutral diamine MV 0 respectively in the chosen media (60 vol.% aqueous DMSO) as described in the literature [53] (Scheme 1).…”

“…If the redox-switching interaction of MVCA 8? with tetraanion SCA 4-occurs during the second reduction step of MVCA [53], the binding of the tetraanionic ferrocyanide switches onto the first reduction step. Probably, SVA 4-and MVCA are more complementary to each other, because the interacting units are located on a similar calixarene platform.…”

A binding of ferrocyanide ([Fe(CN) 6 ] 4-) with octa-cationic tetra(viologen) calix [4] resorcine (MVCA 8? ) and its ''model'' compound--dimethyl viologen (MV 2? ) has been studied by cyclic voltammetry in DMSO-H 2 O media (60 vol.% aqueous DMSO, 0.1 M NaClO 4 ). It was found that MV 2? does not interact with ferrocyanide. By contrast, a reversible redox-switchable interaction between [Fe(CN) 6 ] 4-and MVCA 8? has been observed. MVCA 8? forms a 1:1 supramolecular complex MVCA 8? :[Fe(CN) 6 ] 4-with ferrocyanide while its reduced forms (MVCA 4?Á and MVCA 0 ) do not interact with the tetraanion. The switching of the ferrocyanide binding is also observed in the one electron oxidation of [Fe(CN) 6 ] 4-to [Fe(CN) 6 ] 3-. It has been shown, that the calix [4]resorcine in its partial and fully reduced forms and its complex with ferrocyanide form welldefined nanoscale multi-layer films on the electrode surface.

A novel class of self-assembling nanoparticles is formed with viologen-resorcin[4]arene cavitands; the association model is strongly controlled by their hydrophobicity. Interestingly, the cavitand assemblies are designed through click chemistry to form self-assembled noncovalently connected aggregates through counterion displacement. The iodide and benzoate ions are utilized as strongly polarizable counterions to induce cavitand self-assembly. The counterion-mediated decrease in hydrophilicity of the viologen-resorcin[4]arenes is the underlying trigger to induce particle formation. These particles can be used as nanocontainers and find their applications in delivery systems.
