Abstract Mono-hydroxylated perylene diimide derivative radical anion (PDI2•−) was synthesized in the presence of Potassium carbonate, dimethylformamide with trace H2O. PDI2•− and PDI2 can convert to each other by regulating pH value and solvents. Furthermore, the PDI2•− can be applied in colorimetric chemodosimeter for the rapid detection of some heavy metal ion, and show high sensitivity for Fe3+. The limits of detection of Fe3+ was 1.38 ppm and response time of 1 min.

氢键构建的苝二亚胺自由基阴离子及其比色化学剂量计快速检测Fe3+

摘要 在碳酸钾、二甲基甲酰胺和微量水存在下合成了单羟基化苝二酰亚胺衍生物自由基阴离子(PDI2•-)。PDI2•−和PDI2可以通过调节pH值和溶剂相互转化。此外，PDI2•−可应用于比色化学剂量计中，对某些重金属离子进行快速检测，对Fe3+显示出高灵敏度。Fe3+ 的检测限为 1.38 ppm，响应时间为 1 分钟。
