Synthesis and Oxidation of Triarylamine Derivatives Bearing Hydrogen-Bonding Groups

Hydrogen-bonding triarylamines, 4-(<i>N,N</i>-bis(4-methoxyphenyl)amino)benzoic acid (<b>TPA1</b>), 5-(<i>N,N</i>-bis(4-methoxyphenyl)amino)isophthalic acid (<b>TPA2</b>), and <i>N</i>-(4-(1<i>H</i>-benzimidazol-2-yl)phenyl)-<i>N,N</i>-bis(4-methoxyphenyl)amine (<b>BImTPA</b>), were synthesized as radical cation precursors. <b>TPA1</b> and <b>TPA2</b> are readily p-doped by AgSbF<sub>6</sub> to give highly persistent radical cations. Poor solid-state spin yields of the radical cation from <b>BImTPA</b> may be due to spin delocalization.
