摘要：
A series of arylaminofluorene derivatives (DTFA-1, TTFA-2, TAFB-3, and TAFA-4) were synthesized, and the generation of their corresponding arylaminium cation radicals was readily achieved by Cu(ClO4)(2) in CH3CN. Moreover, the cation radicals were stable at ambient temperature with substantially long life times and exhibited distinct colors. The oxidation mechanism and spectroscopic features of the resulting cation radicals were probed by UV-vis-NIR spectroscopy and electron spin resonance experiments.
