The 13C NMR spectra of some 1- and 2-substituted perimidines and perimidinium salts are discussed and assigned. Although the spectra of most of the 2-substituted perimidines are comparatively simple, several examples display 13C and 1H spectral characteristics indicative of inhibition of prototropic tautomerism.
A novel anthracene-based tetraperimidine hexafluorophosphate 3 was prepared, and its structure was determined through X-ray analysis, HRMS as well as 1H and 13C NMR spectroscopy. In the cationic moiety of 3, two (N-ethylperimidinyl-C2H4)2NCH2- arms were attached to the 9- and 10-positions of anthracene. In addition, compound 3 was used as a chemosensor to research the ability to recognize Cr3+ through
制备了一种基于蒽的新颖的四亚丙基六氟磷酸酯3,并通过X射线分析,HRMS以及1H和13C NMR谱确定了其结构。在3的阳离子部分中,两个(N-乙基亚丙基-C 2 H 4)2 NCH 2-臂连接至蒽的9位和10位。此外,化合物3用作化学传感器,以研究通过荧光和UV滴定,HRMS以及1H NMR和IR光谱识别Cr3 +的能力。结果表明3是有效的Cr3 +化学传感器。
