从1-芳氧基蒽醌和4'-氨基苯并-15-冠-5醚光化学制备了一系列互变异构的生色团。所有合成的染料都可以将锶和钡阳离子结合为三明治型2:1配体-金属配合物,与相应的1:1配合物(K 1:1)相比,其显示出更高的稳定性常数(K 2 :1),即K 2: 1 / K 1:1比率达到10(在MeCN中)。对于未取代的苯并-15-冠-5醚的相关配合物,观察到相反的关系,即K 2:1 < K 1:1。用分光光度法研究了三明治复合物,11 H NMR光谱,质谱和密度泛函理论计算。在K 2:1 / K 1:1比与三明治复合物中短堆积触点数之间发现相关性。

4,4'- and 4,5 -Bis(1-hydroxy-2-R-9,10-anthraquinone-9-imino)dibenzo-18-crown-6 ethers (novel alkaline-earth cation chemosensors) were synthesised by the photochemical condensation of 1-aryloxy-2-R-9,10-anthraquinones with aromatic diamines containing a 18-crown-6 ether bridge in benzene at room temperature.
