Abstract

The aminolysis reactions of hexachlorocyclotriphosphazene, [N₃P₃Cl₆] (1a) and dispiro-2,2′-biphenoxydichlorocyclotriphosphazene [N₃P₃Cl₂[(2,2′-biphenoxy)₂] (1b) with 6-aminoquinoline (2) were carried out to examine the spectroscopic properties of cyclotriphosphazene derivatives combined with 6-aminoquinoline. For the first time, two new aminoquinoline-substituted cyclotriphosphazene derivatives (3a, b) were obtained in this study. Both compounds (3a, b) have been characterized by elemental analysis, FT-IR analysis, MALDI-TOF mass spectrometry, ¹³C, ¹H, and ³¹P NMR spectroscopies. The molecular structure of 3b has been confirmed by single crystal X-Ray crystallography. The crystal structure of 3b was investigated in detail to determine the remarkable intermolecular interactions. Furthermore, the photophysical properties of compounds 3a and 3b were determined by using UV/vis and fluorescence spectroscopies.

新型氨基喹啉修饰环三磷杂烯的合成、表征及光谱性质

通过六氯环三磷腈[N3P3Cl6] (1a)和二吡咯-2,2′-联苯氧二氯环三磷腈[N3P3Cl2[(2,2′-联苯氧基)2](1b)与6-氨基喹啉(2)的氨解反应，考察了6-氨基喹啉与环三磷腈衍生物的光谱性质。本研究首次获得了两个新的氨基喹啉取代环三磷腈衍生物(3a, b)。两种化合物(3a, b)通过元素分析，FT-IR分析，MALDI-TOF质谱，13C, 1H和31P NMR谱进行了表征。用单晶x射线晶体学证实了3b的分子结构。详细研究了3b的晶体结构，确定了其显著的分子间相互作用。此外，利用紫外/可见光谱和荧光光谱测定了化合物3a和3b的光物理性质。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
