Some new pyrazino-fused 1,4,5,8-tetraazafulvalenes of type (3-5) were synthesized and their structures were confirmed by IR, UV-VIS, 1 H NMR spectra and elemental analysis. The X-Ray crystal structure analysis of a singlecrystal of derivative (3c) revealed a nearly ideal planarized heterofulvalene subunit. The new prepared tricyclic tetraazafulvalenes of type (3) show strong red fluorescence at 605
合成了一些新型吡嗪稠合1,4,5,8-四氮杂富瓦烯(3-5),并通过IR、UV-VIS、1 H NMR光谱和元素分析证实了它们的结构。衍生物 (3c) 的单晶的 X 射线晶体结构分析揭示了一个近乎理想的平面化异富瓦烯亚基。新制备的 (3) 型三环四氮杂富瓦烯在 605 nm 处显示出强烈的红色荧光。
