A fluorescent and colorimetric chemosensor based on rhodamine 6G was designed, synthesized, and characterized. Based on a two-step reaction, the chemosensor effectively recognized Hg. The interaction between the chemosensor and Hg was confirmed by ultraviolet-visible spectrophotometry, fluorescence spectroscopy, electrospray ionization-mass spectrometry, Fourier-transform infrared spectroscopy, and frontier molecular orbital calculations. The chemosensor was also incorporated into test strips and silica gel plates, which demonstrated good selectivity and high sensitivity for Hg.
设计、合成并表征了一种基于罗丹明6G的荧光和比色化学传感器。基于两步反应，该化学传感器能有效识别汞。通过紫外可见分光光度法、荧光光谱法、电喷雾电离质谱法、傅里叶变换红外光谱法和前线分子轨道计算，证实了化学传感器与汞之间的相互作用。该化学传感器还被整合到测试条和硅胶板中，对汞表现出良好的选择性和高灵敏度。
