properties of obtained compounds and their 2-phenylquinazoline counterpart have been investigated in both solution and the solid state. Quinazoline chromophores exhibited positive emission solvatochromism, and the collected data were analyzed using the Lippert-Mataga equation, as well as Kosower and Dimroth/Reichardt scales. Moreover, halochromic properties upon addition of trifluoroacetic acid have been examined;
设计并合成了2位带有吡啶基或喹啉基残基的4-(4-氨基苯基)-2-azinylquinazolines。已在溶液和固态下研究了所得化合物及其 2-苯基喹唑啉对应物的基本光物理性质。喹唑啉发色团表现出正发射溶剂化显色性,收集的数据使用 Lippert-Mataga 方程以及 Kosower 和 Dimroth/Reichardt 量表进行分析。此外,还检查了添加三氟乙酸后的卤化特性;结果表明,由于 2-炔基喹唑啉片段的质子化,发色团在酸性介质中显示出红移发射带。还分析了合成杂环对金属阳离子的发光响应。
