The synthesis of calix[4]- and -[6]arene derivatives P6(H)22+·(Cl–)2, V4(H)24+·(Cl–)2·(I–)2, V6(H)24+·(Cl–)2·(I–)2 bearing N-linked pyridinium (P) viologen (V) units at the upper rim is described here. A rare example an anionic conformational template reported for p-pyridiniumcalix[6]arene P6(H)22+, which adopts a 1,3,5-alternate conformation in presence chloride anions. Derivatives V6(H)24+·(Cl–)2·(I–)2, V4(H)24+·(Cl–)2·(I–)2 show negative solvatochromism, while their UV–vis acid–base...
