两个新型1,3-硒唑酰腙的合成及其对醋酸根离子的特性荧光识别
Synthesis of Two Novel 1,3-Selenazole Carbonyl Hydrazones and Their Specific Fluorescent Recognition Toward Acetate Ions
摘要
Abstract
Two novel 1,3-selenazole carbonyl hydrazones(SAF1, SAF2)were synthesized and their structures were confirmed by infrared spectrometry and nuclear magnetic resonance.Monitoring of nine common anions using probes SAF1 and SAF2 was performed via ultraviolet-visible and fluorescent spectra. When acetate ions(AcO-)were added,a new absorption peak of SAF1 and SAF2 was found at 500 nm and 414 nm,respectively.The color of SAF1 and SAF2 solutions changed from pale yellow to red and yellow, respectively.These results show naked eye identification of AcO -.In fluorescent spectra, a strong emission peak at 417 nm is found with the turn-on effect.The lowest limit of detection for AcO -reaches 10 -5mol/L. The binding constants of SAF1 and SAF2 with AcO -are 3.03 ×104and 1.42 ×104L/mol, respectively. SAF1 and SAF2 are expected to be specific fluorescent probes toward AcO -.关键词
