Based on thermogravimetric characteristics first obtained for the model 6H-indeno [1,2-b]quinoline, the scheme of thermal conversions of this compound in the temperature range 20–700 °C has been proposed, and the limit of its thermal stability (∼300 °C) has been determined. This temperature is recommended as the optimum for synthesizing fused benzoaza(diaza)fluorenes. Based on the results of X-ray
根据首先获得的模型 6H-茚并 [1,2-b] 喹啉的热重特性,提出了该化合物在 20-700 °C 温度范围内的热转化方案,以及其热稳定性的极限( ∼300 °C) 已确定。该温度被推荐为合成稠合苯并氮杂(二氮杂)芴的最佳温度。根据X射线结构分析结果,所研究的茚并喹啉分子形成中心对称对,呈(110)层排列。分子取向无序。观察到的这些分子的自缔合类似于具有 π-过量和 π****- 缺陷片段的稠合杂环系统的 π-π 缔合。
