A universal photoinduced electron transfer (PeT) approach to construct dual-fluorescence materials is presented. Impressively, the o-carborane dyads show multicolour fluorescence from single molecules due to the competition of nonradiative relaxation channels between internal conversion (IC) and PeT. Importantly, the multicolour, flexible and transparent films as well as an anticounterfeiting application using this dyad are well demonstrated.

基于邻碳硼烷二元激发依赖电子转移过程的多色荧光

提出了一种构建双荧光材料的通用光致电子转移 (PeT) 方法。令人印象深刻的是，由于内部转换 (IC) 和 PeT 之间的非辐射弛豫通道的竞争，邻碳硼烷二元显示出来自单个分子的多色荧光。重要的是，多色、柔韧和透明的薄膜以及使用这种对偶的防伪应用得到了很好的证明。
