摘要

在各种溶剂中记录了 N-(3,5-二氯-4-羟基苯基)-2,4,6-三苯基吡啶鎓高氯酸盐及其去质子化甜菜碱 4-(2,4,6-三苯基吡啶)-2、6-二氯苯酚(沃尔夫贝斯的 ET(33) 染料)在各种溶剂中的核磁共振波谱进行了记录和分析,以寻找反映其溶解磁性特征的溶剂依赖性位移,并将其与这种重要溶解变色染料的著名紫外-可见光谱行为进行比较。虽然 ET(33) 及其酚类前体在不同溶剂中的核磁共振光谱与其紫外-可见光谱反应的相关性很低,但它们提供了有关特定结构特征和溶质-溶剂相互作用的宝贵信息,而这些信息是它们的紫外-可见光谱所无法提供的。

The Solvatomagnetism of ET(33) Betaine and of Its Phenolic Precursor

The 1H and 13C NMR spectra of the N-(3,5-dichloro-4-hydroxyphenyl)- 2,4,6-triphenylpyridinium perchlorate and of its deprotonated betaine 4-(2,4,6-triphenylpyridinio)-2,6-dichlorophenolate (Wolfbeis's ET(33) dye) were recorded in various solvents and analyzed in search of solvent-dependent shifts that characterize their solvatomagnetism, which was compared with the well-known UV–vis spectral behavior of this important solvatochromic dye. Although the NMR spectra of ET(33) and its phenolic precursor in different solvents correlated only poorly with their UV–vis spectral responses, they provided valuable information on specific structural features and solute–solvent interactions that are not available from their UV–vis spectra.

期刊介绍: MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
