Abstract A smart nopinone-based fluorescent probe BIPA for the detection of hydrazine was developed which exhibited excellent sensitivity and specifity. The detection limit of BIPA for hydrazine was calculated as low as 7.9 × 10−8 M which was much lower than 3.2 × 10−7 M (stipulated by U.S. Environmental Protection Agency). The interference test showed that other competitive analytes could hardly interfere the detection of hydrazine in a complex environment. With the presence of hydrazine, the color of BIPA changed from colorless to blue-green under 365 nm UV light, and the solution exhibited a remarkable color change from bright yellow to colorless under daylight. The detection towards hydrazine could be valid in a wide pH range from 5 to 12. BIPA-coated filter paper could distinguish hydrazine from other analytes, and it could be applied in detecting hydrazine in real water samples. Overall, this work provided a new valuable fluorescent probe for detecting hydrazine.

一种基于诺品酮的智能荧光探针，用于水和植物中肼的比色和荧光检测，具有高灵敏度和选择性

摘要 开发了一种用于检测肼的智能nopinone荧光探针BIPA，该探针具有良好的灵敏度和特异性。经计算，BIPA 对肼的检出限低至 7.9 × 10-8 M，远低于美国环保署规定的 3.2 × 10-7 M。干扰测试表明，其他竞争性分析物在复杂环境中几乎无法干扰肼的检测。在肼的存在下，BIPA在365 nm紫外光下颜色由无色变为蓝绿色，溶液在日光下呈现显着的颜色由亮黄色变为无色。对肼的检测可以在 5 到 12 的宽 pH 范围内有效。 BIPA 涂层滤纸可以将肼与其他分析物区分开来，可用于实际水样中肼的检测。总的来说，这项工作为检测肼提供了一种新的有价值的荧光探针。
