摘要:
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 Cu2+ or Hg2+. 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 Pb2+, Sc3+ etc. (c) 2013 Bang-Tun Zhao and Wei-Min Zhu.
