Reduction of 3(2+) with zinc gave the corresponding cyclization products (4), from which dications (3 2,) were regenerated upon oxidation. Cyclic voltammetry also showed the interconversion between 3(2+) and 4. Variable-temperature (1)H NMR measurements revealed that the rotational barriers of the xylyl units in the neutral states (4) are higher than those in the dication states (3(2+))., Article, HETEROCYCLES. 74: 251-257 (2007)}, pages = {251--257}, title = {Synthesis and properties of bis(1,3-benzodithiole)-type redox systems containing a xylyl rotator unit: A new type of redox-responsive molecular rotor}, volume = {74}, year = {2007} }
