| Abstract: | o-Aminophenol, p-toluic acid and polyphosphoric acid(PPA) were refluxed to prepare the intermediate L1 at 220 ℃ in N2. The intermediate L2 was obtained by reacting with N-bromosuccinimide(NBS) and L1, which reacted with triphenylphosphine to give L3. Intermediate L4 was synthesized by Wittig reaction of L3 and 3-pyridinecarboxaldehyde. Finally, six novel compounds 1~6 were synthesized by the methylation reaction and anion exchange reaction. The structures were characterized by 1H NMR, 13C NMR, FT-IR and HR-MS. The crystal structure of compound 1(CCDC: 1838541) indicated that its cationic portion owned good planarity. UV-Vis absorption and fluorescence emission spectra showed that 1~6 possessed good optical properties in different polarity solvents. |
