摘要: 合成了一种材料N,N′-二苯并咪唑-苝二酰亚胺(PV),经多次真空升华提纯,产率为68%,纯度达95%以上。利用傅里叶变换红外光谱(FTIR)、紫外/可见吸收光谱(UV/Vis)、元素分析、热失重分析(TG)对该产物的结构和性能进行了表征。结果表明:苝四甲酸二酐(PTCDA)与邻苯二胺反应,易转化成二苯并咪唑苝类衍生物。该PV材料在450~750 nm范围内有两个强的吸收峰,其初始热分解温度约为510 ℃,热稳定性较好。Abstract: N,N′-diphenyl glyoxaline-3, 4, 9, 10-perylene tetracarboxylic diimide(PV) was synthesized from perylene-3,4,9,10-tetracarboxylic acid bisanhydride and o-phenylenediamine. The product was purified by vacuum sublimation with 68% yield and more than 95% purity and characterized by FTIR, UV/Vis, elemental analysis and TG. Results showed that PV could be easily obtained from PTCDA with high yield. UV/Vis spectra of PV’s DMF solution had two strong absorption peaks in 450 to 750 nm. The onset decomposition temperature of PV was about 510 ℃, which indicates that PV has high thermal stabilization.
