charges). The solvation effect of different organic liquids on the absorption spectra of the reagent has been studied. 1H, 13C, COSY, HSQC and HMBC NMR, UV–Vis and IR spectra were used to confirm the reagent structure. It has been shown that NBnTAN forms complex compounds with a number of transition metals, allowing the development of selective methods for the determination of these metals.
首次合成了一种新的噻唑基偶氮结构,即1-[(5-(3-硝基苄基)-1,3-噻唑-2-基)二氮烯基]萘-2-醇(NBnTAN)。通过光谱,DFT和半经验方法,通过计算不同的电子描述符(芳香性,前沿分子轨道,偶极矩,部分原子电荷),研究了这种新型染料的几何参数和性质。研究了不同有机液体对试剂吸收光谱的溶剂化作用。1 H,13 C,COSY,HSQC和HMBC NMR,UV-Vis和IR光谱用于确认试剂结构。已经表明,NBnTAN与许多过渡金属形成复杂的化合物,从而允许开发测定这些金属的选择性方法。
