Hydrogen-bonding triarylamines, 4-(N,N-bis(4-methoxyphenyl)amino)benzoic acid (TPA1), 5-(N,N-bis(4-methoxyphenyl)amino)isophthalic acid (TPA2), and N-(4-(1H-benzimidazol-2-yl)phenyl)-N,N-bis(4-methoxyphenyl)amine (BImTPA), were synthesized as radical cation precursors. TPA1 and TPA2 are readily p-doped by AgSbF6 to give highly persistent radical cations. Poor solid-state spin yields of the radical
氢键三芳基胺,4-(N,N-双(4-甲氧基苯基)氨基)苯甲酸(TPA1),5-(N,N-双(4-甲氧基苯基)氨基)间苯二甲酸(TPA2),和Ñ -合成了(4-(1 H-苯并咪唑-2-基)苯基)-N,N-双(4-甲氧基苯基)胺(BImTPA)作为自由基阳离子前体。TPA1和TPA2容易被AgSbF 6 p掺杂以产生高度持久的自由基阳离子。来自BImTPA的自由基阳离子的固态自旋产率差,可能是由于自旋离域作用。
