D2-symmetric binaphthyl-bridged pyrenophanes have been synthesized with face-to-face pyrene rings. Matching the type and position of the linkers led to the pyrenophane exhibiting intensecircularlypolarizedluminescence with a |glum| value reaching 0.053. This effect arose because of the D2 symmetry of the dye, which resulted in the binaphthyl moieties producing a unidirectionally twisting pyrene
D 2 -对称联萘桥联的芘已合成了具有面对面芘环。匹配接头的类型和位置导致芘显示出强烈的圆偏振发光,具有 | 克拉姆| _ 值达到 0.053。这种效应是由于染料的D 2对称性引起的,这导致联萘部分产生具有完全平行的电和磁跃迁偶极矩的单向扭曲芘准分子。
