Benzo[h]imidazo[1,2-a]quinolines and 1,2a-diazadibenzo[cd,f]azulenes were prepared from a common intermediate by regioselective cycloisomerization reactions. The selectivity was controlled by the choice of Brønsted acid and solvent. The optical and electrochemical properties of the products were studied by UV/vis, fluorescence, and cyclovoltammetric measurements. The experimental results were complemented
苯并[h]咪唑并[1,2-a]喹啉和1,2a-二氮杂二苯并[cd,f]甘菊环由常见中间体通过区域选择性环异构化反应制备。选择性通过布朗斯台德酸和溶剂的选择来控制。通过紫外/可见光、荧光和循环伏安测量研究了产品的光学和电化学性质。实验结果得到了密度泛函理论计算的补充。
