Optimization of Sensing Performance in DCN-Based Fluorescent Sensors

2,6-二氯-4-硝基苯胺(DCN)是一种典型的氯代硝基苯胺类除草剂，但是其在提高农作物产量的同时，也会对人体健康、环境、生态系统和经济带来负面影响。因此，开发一种可以快速、灵敏、便捷的传感器来检测环境中的农药是很有必要的。因此，本文选择一种具有较强蓝绿色发光的杂金属化合物，将其制备为PMMA杂化薄膜，用于特异性检测DCN，并在这种化合物内部封装罗丹明B得到具有双发射特性的复合物，提高了对于DCN的传感能力。2,6-Dichloro-4-nitroaniline (DCN) is a typical chlorinated nitroaniline herbicide. While it enhances crop yields, it also poses negative impacts on human health, the environment, ecosystems, and the economy. Therefore, it is essential to develop a rapid, sensitive, and convenient sensor for detecting pesticides in the environment. In this study, we selected a strongly blue-green-emitting heterometallic compound and incorporated it into a PMMA hybrid film for the specific detection of DCN. Additionally, Rhodamine B was encapsulated within this compound to create a dual-emission composite, thereby enhancing the sensing capability for DCN.
