The detection of boron in natural water and wastewaters is still limited to a few methods, requiring a compromise between sensitivity, reliability and accessibility. Here we present a novel polymeric fluorescent boron sensor with excellent water solubility, boron sensitivity, ease of handling, which can be easily recovered and reused. The new off–on fluorescent boron sensor is able to detect and quantify
天然水和废水中硼的检测仍然仅限于几种方法,需要在灵敏度,可靠性和可及性之间进行折衷。在这里,我们介绍了一种新颖的高分子荧光硼传感器,该传感器具有出色的水溶性,硼敏感性,易于处理,可以轻松回收和再利用。新型的关闭式荧光硼传感器能够检测和定量水中ppb的硼,对于硼酸和苯基硼酸,检出限为10 ppb。传感器是通过将甲基丙烯酸与可聚合的不对称六取代的三亚苯基(通过联苯和邻苯二酚前体的氧化环化获得的)共聚而制备的。
