Simple pyrene-based chemosensors 1 to 3, were synthesized from pyrene-1-carboxaldehyde and they were characterized using various spectroscopic techniques like UV-Vis, FT-IR, Mass, H NMR and C NMR. Among synthesized receptors, the receptor 1 shows high selectivity towards Hg ions. Further, the high selectivity of receptor 1 towards Hg ions in the presence of various other interfering metal ions like Ni, Zn, Mn, Co, Cu, Cr, Fe, Al, Ag, Fe, Cd, Mg, Pb, Ca, Na, K was confirmed by UV-Vis and fluorescence methods. The detection limit for Hg ions was found to be 0.270 μM. The chemodosimetric irreversible hydrolysis of the receptor 1 in the presence of Hg was studied by UV/Vis, fluorescence, FT-IR, LC-MS, H NMR and theoretical DFT study. Further, the real life applications of receptor 1 for the determination of Hg ions were demonstrated by UV-Vis method.
简单的芘基化学传感器1至3由芘-1-甲醛合成，并使用紫外可见光谱、傅里叶变换红外光谱、质谱、氢核磁共振和碳核磁共振等各种光谱技术对其进行了表征。在合成的受体中，受体1对汞离子表现出高选择性。此外，通过紫外可见光谱和荧光方法证实了受体1在存在镍、锌、锰、钴、铜、铬、铁、铝、银、铁、镉、镁、铅、钙、钠、钾等各种其他干扰金属离子的情况下对汞离子具有高选择性。发现汞离子的检测限为0.270 μM。通过紫外可见光谱、荧光、傅里叶变换红外光谱、液相色谱-质谱、氢核磁共振和理论密度泛函理论研究了受体1在汞存在下的化学计量不可逆水解。此外，通过紫外可见光谱法展示了受体1在测定汞离子方面的实际应用。
