Abstract
Two new cavitands bearing four upper-rim tetrathiafulvalene (TTF) units were synthesized. One of these cavitands was used to prepare a redox-active hemicarcerand containing four TTF subunits covalently appended to its equatorial region. Preliminary electrochemical characterization data show that the four TTF residues in all these compounds behave as independent, non-interacting groups in their heterogeneous electron transfer reactions.
