T. Suzuki et al., BIPHENYL-TYPE ELECTRON-ACCEPTORS EXHIBITING DYNAMIC REDOX PROPERTIES - A NOVEL ELECTROCHROMIC SYSTEM WITH WRITE PROTECT OPTION, Chemical communications, (13), 1998, pp. 1331-1332
A novel redox pair undergoing reversible C-C bond making/ breaking has
been constructed based on a bis(dicyanovinyl)biphenyl derivative and
a dianion with the dihydrophenanthrene skeleton; further cyclization o
f the latter to an enaminonitrile endows the 'write protect' option to
its electrochromic response.
