| description | The invention discloses a fluorescent chemical sensor for detecting catechol, and a preparation method thereof, which belong to the technical fields of nanometer material preparation and chemical analysis. A carbon dot containing amidogen on the surface is prepared from citric acid and diethylenetriamine through a one-step hydrothermal method, and then is functionalized by utilizing 4-carboxyphenylboronic acid. The prepared functionalized fluorescent carbon dot has the average diameter being 7.5nm, the fluorescence of the functionalized carbon dot is not changed remarkably, and after the catechol is added, the fluorescence is quenched caused by a static quenching effect, so that the functionalized carbon dot can realize specific recognition and the detection on the catechol, is high in sensitivity, and has a wide application prospect.
本发明提供了种检测邻本二酚的荧光化学传感器及其制备方法，属于纳米材料制备和化学分析技术领域。本发明以柠檬酸、二乙烯三胺通过步水热的方法，制备了表面含有氨基碳点，然后用4-羧基苯硼酸功能化该碳点。所制备的功能化的荧光碳点平均直径为7.5nm，功能化之后的碳点荧光无明显变化，当加入邻苯二酚之后由于静态猝灭效应导致其荧光猝灭，从而可实现对邻苯二酚的特异性识别 |
