on this idea, we synthesized a novel fluorene-based fluorescent compound with a restricted rotor rotation on the stator through the Suzuki coupling reaction. The luminescence effect was evaluated by comparing its fluorescence intensity with that of the control compound. Finally, theoretical calculations showed that the presence of methyl groups hindered the thermal rotation of the fluorenyl groups. Thus
目前,我们已经意识到聚集诱导发射(AIE)通过限制旋转来减少分子间或分子内的能量损失来达到荧光增强的目的。基于这一想法,我们通过 Suzuki 偶联反应合成了一种新型芴基荧光化合物,该化合物在定子上具有受限的转子旋转。通过比较其荧光强度与对照化合物的荧光强度来评估发光效果。最后,理论计算表明甲基的存在阻碍了芴基的热旋转。因此,结果表明该化合物的荧光优于对照化合物。已开发出一种用于高效 AIE 基荧光发光剂的新合成途径。
