摘要: 芘和苯甲醛,在对甲基苯磺酸作用下,生成了B阶COPNA树脂。用红外光谱、核磁共振氢谱及碳谱对其结构进行了表征。B阶COPNA树脂经在惰性气氛中500、600和800℃的热处理后,得到不溶不熔的COPNA树脂。电子自旋共振谱(ESR)测试表明,其稳定自由基浓度最高可达2.28×1022spins/g.

Abstract: The B stage codensed polynuclear aromatic resin(B-COPNA)was synthesized from pyrene and benzaldehyde in the presence of p-toluenesulfonic acid. Its structure was characterized by IR, 1H NMR and 13C NMR measurements. Results showed that the polymer possesses triarylmethane structure. On heating under inert gas at 500℃, 600℃ and 800℃ COPNA resin dehydrogenated and converted to an insoluble and infusible one, which, as ESR results shows, exhibits an obvious paramagnetic property and very high concentration of stable free radicals: 2.28×1022 spins/g.
