合成了3,4 ' -双[双（对叔丁基苯基）氨基]二苯乙烯1a和3,4 ' -双[双（对甲氧基苯基）氨基]二苯乙烯1b。通过电化学测量分析了1的氧化反应，揭示了通过双电子转移反应可逆地形成了阳离子自由基2。1与NOBF4的化学氧化也得到了2（阳离子自由基）；紫外/可见和ESR光谱支持胺自由基的形成，无任何副反应。双自由基的磁化率、磁化率和ESR ΔMs =±2信号表明三重态基态具有较大的三重态-单线态能隙。
3,4′-Bis[bis(p-t-butylphenyl)amino]stilbene 1a and 3,4′-bis[bis(p-methoxyphenyl)amino]stilbene 1b were synthesized. The oxidation of 1 was analyzed by electrochemical measurements, which revealed the reversible formation of the bis(cation radical) 2 via a two-electron transfer reaction. The chemical oxidation of 1 with NOBF4 also gave the bis(cation radical) 2; UV/vis and ESR spectroscopies supported aminium radical formation without any side reaction. Magnetization, magnetic susceptibility, and the ESR ΔMs = ±2 signal of the biradicals indicated triplet ground states with a large triplet-singlet energy gap.
