improved protocol for the synthesis of bis(indolyl)methanes using 6 mol% [BCMIM][Cl] ionic liquid via facile, one-pot, metal-free synthesis in aqueous ethanol at ambient temperature. In 15–55 min, a series of 48 derivatives were obtained in up to 94 % yields and were characterized using several spectroscopic techniques. UV–visible and fluorescence spectroscopies were used to investigate the photophysical behaviour
在此,我们提出了一种改进的方案,使用 6 mol% [BCMIM][Cl] 离子液体在环境温度下在乙醇水溶液中进行简单、一锅、无金属的合成来合成双(吲哚基)甲烷。在 15-55 分钟内,获得了一系列 48 种衍生物,收率高达 94%,并使用多种光谱技术进行了表征。使用紫外可见光谱和荧光光谱研究合成的双吲哚衍生物的光物理行为。吸收光谱和发射光谱的波长分别为 298-379 nm 和 327-352 nm。理论计算显示出与实验研究相似的趋势。使用 AutoDock Vina 评估合成的衍生物与牛血清白蛋白 (BSA) 的结合亲和力。结果显示亲和力范围为-7.9 至-10.5 kcal mol。
