Two tetrathiafulvalene-calix[4]arene assemblies(TTF-calix-1 and TTF-calix-2) have been synthesized by the click reaction.Both their cyclic voltammograms show,as expected,two one-electron quasi-reversible redox behavior.The UV-vis absorption spectra studies show that these two assemblies undergo progressive oxidation at the TTF moiety in presence of increasing amounts of Cu~(2+) or Hg~(2+). Moreover,the absorption studies show intermolecular electron transfer between compounds TTF-calix- 1 or TTF-calix-2 and p-chloranil may be promoted by specific metal ions such as Pb~(2+),Sc~(3+) etc.

Two tetrathiafulvalene-calix [4] arene assemblies (TTF-calix-1 and TTF-calix-2) have been synthesized by the click reaction. Both their cyclic voltammograms show, as expected, two one-electron quasi-reversible redox behavior. UV-vis absorption spectra studies show that these two assemblies undergo progressive oxidation at the TTF moiety in presence of increasing amounts of Cu ~ (2+) or Hg ~ (2+). Moreover, the absorption studies show intermolecular electron transfer between compounds TTF -calix-1 or TTF-calix-2 and p-chloranil may be promoted by specific metal ions such as Pb ~ (2 +), Sc ~ (3+) etc.
