An electrochromic tristable molecular switch
A tristable [2] catenane, composed of a macrocyclic polyether incorporating 1, 5-
dioxynaphthalene (DNP) and tetrathiafulvalene (TTF) units along with a 4, 4′-bipyridinium
(BIPY•+) radical cation as three very different potential recognition sites, interlocked
mechanically with the tetracationic cyclophane, cyclobis (paraquat-p-phenylene)(CBPQT4+)
, was synthesized by donor–acceptor templation, employing a “threading-followed-by-
cyclization” approach. In this catenane, movement of the CBPQT4+ ring in its different redox …
