摘要：

The synthesis Of nitrogen cation-doped poly cyclic aromatic hydrocarbons (PAHs) having a variety of counteranions is reported via the trimethylsilyl (TMS)-promoted, intramolecular aromatic nudeophilic substitution (SNAr) reaction of fluoroarenes and pyridine groups. The electrochemical properties and optical properties of the obtained nitrogen cation-doped PAHs were studied in detail, clarifying that they have low-lying LUMO levels and good emission properties derived from. the incorporation of planar N-arylpyridinium moieties.
