摘　　要：Two tetrathiafulvalene-calix[4]arene assemblies （TTF-calix-1 and TFF-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 TFF moiety in presence of increasing amounts of Cu2＋ or Hg2＋. Moreover, the absorption studies show intermolecular electron transfer between compounds TrF-calix- I or TI＇F-calix-2 and p-chloranil may be promoted by specific metal ions such as Pb2＋, Sc3＋ etc.Two tetrathiafulvalene-calix[4]arene assemblies （TTF-calix-1 and TFF-calix-2） have been synthesized by the click reaction.
