This work describes a simple and sensitive fluorescent method for detection of hydroquinone utilizing conjugated polymer nanoparticles (CPNs). The CPNs serve both as a catalyst to accelerate the conversion of hydroquinone to benzoquinone and a fluorescent probe. In the presence of hydroquinone, the fluorescence of CPNs can be effectively quenched by benzoquinone. The detection limit of hydroquinone was down to 5 nM and excellent selectivity toward possible interferences was obtained. This method was successfully applied for hydroquinone detection in lake water and satisfactory results were achieved.
本工作描述了一种利用共轭聚合物纳米粒子（CPNs）检测对苯二酚的简单灵敏的荧光方法。CPNs 既可用作催化剂加速对苯二酚转化为苯醌，又可用作荧光探针。在对苯二酚存在下，CPNs 的荧光可被苯醌有效猝灭。对苯二酚的检测限低至 5 nM，并获得了对可能干扰物的优异选择性。该方法成功地应用于湖水对苯二酚的检测，获得了令人满意的结果。
