3-phosphonocoumarins were performed, and the effect of the substituents in the aryl moiety was evaluated. The structures possessing promising fluorescent properties were successfully synthesized via Suzuki and Sonogashira cross-coupling. The synthetic protocol was also applied for the phosphorous chemoisomer of 3-phosphonocoumarin, 1,2-benzoxaphosphorin, and their carboxylate analogues. The optical properties of the
对一些芳基取代的 3-phosphonocoumarins 的光谱特性进行了量子化学计算,并评估了芳基部分取代基的影响。通过 Suzuki 和 Sonogashira 交叉偶联成功合成了具有良好荧光特性的结构。该合成方案还适用于 3-phosphonocoumarin、1,2-benzoxaphosphorin 及其羧酸盐类似物的磷化学异构体。芳基化和炔基化产物的光学性质通过实验确定。获得的量子化学和实验结果为通过改变其 C-6 位置的取代基来微调含磷香豆素系统的光学性质提供了可能性。
