以苝四酸酐为原料合成了1,7-二溴-3,4,9,10-苝四酸酐(PeryBr_2)、N,N'-二(十二烷基)-1,7-二溴-3,4,9,10-苝四羧酸二酰亚胺(DD-PeryBr_2)和N,N'-二(十二烷基)-1,7-二对叔丁基苯氧基-3,4,9,10-苝四羧酸二酰亚胺(DD-PeryBp_2) 3种苝四羧酸二酰亚胺类化合物,并对其结构和性能利用紫外-可见吸收光谱、傅立叶红外光谱、核磁共振、质谱、热分析和荧光光谱测试技术进行了表征和测试. 结果表明,DD-PeryBp_2能很好的溶于甲苯、氯仿、四氢呋喃等常用有机溶剂. 紫外可见最大吸收波长和荧光最大发射波长分别为548和576 nm. DD-PeryBp_2具有很好的热稳定性,质量损失5%时的温度为433 ℃.
Perylene derivatives PeryBr_2, DD-PeryBr_2 and DD-PeryBp_2 were synthesized from perylene-3,4,9, 10-tetracarboxylic acid bisanhydride and characterized by UV-Vis, FT-IR, ~1H NMR, MS, TGA and fluorescence spectroscopy measurements. The result shows that DD-PeryBp_2 is highly soluble in conventional solvents such as toluene, chloroform and THF. The UV-Vis maximal absorption and fluorescence spectroscopy maximal emission of DD-PeryBp_2 are at 548 nm and 576 nm, respectively. TG measurements show that perylene diimides possess good thermal stability and the temperature at which 5% mass loss is observed in nitrogen is 433 ℃.
