Abstract:
1,3,5-tripyrrolidinobenzene is the first example of an aromatic amine that forms σ dimers during oxidation/reduction cycles [Eq. (1); X- =ClO4- ], and thus turns out to be an efficient molecular switch. Surprisingly, such σ dimers are relatively stable intermediates during the formation of conjugated oligomers and polymers.
