The methylene-bridged triphenylamine 2 has been oxidized to planar radical cation 2 •+ by B(C6F5)3 or Ag+. Further reaction of 2 •+ [Al(ORF)4]− and 2 with trace amounts of silver salt resulted in dication 3 2+, providing a rare example of structurally characterized bis(triarylamine) “bipolarons”. 3...
