|
摘要
以苯偶酰、水合肼以及醛类化合物为起始底物,2步反应高产率合成了苯偶酰腙类席夫碱,采用核磁共振氢谱、碳谱及质谱对其结构进行了表征.此外,分别使用紫外光谱法和荧光光谱法研究了p H值对光谱性能的影响,对常见金属离子的识别性能以及溶剂变化对光谱的影响进行了讨论,光谱性能的研究结果表明,该类化合物可以作为光学染料.
Based on benzoyl,hydrazine hydrate and aldehydes as starting substrates,Benzil monohydrazone schiff bases were synthesized in high yield by two-step reactions,and characterized by 1 HNMR,13 CNMR and MS.In addition,the effects of pH on the spectral properties,the recognition performance of common metal ions and the influence of solvent changes on the spectral properties were studied by using UV spectrometry and fluorescence spectrometry,respectively.The spectral properties showed that the compounds have good properties for practical applications as optical dye.
