A novel kind of expanded tetraphenylethylene (TPE)-carborane-TPE pentad has been synthesized by using two adjacent carborane moieties as central bridges and three TPE units in lateral positions. Its solid-state fluorescence quantum yield was substantially increased to 68.2% by expanding the number of bridges between carborane and TPE. Subsequently, the emission color shifted from blue to orange-yellow (126 nm). Mechanical insights into the electronic structure of the extended TPE-carborane-TPE pentads were obtained from density functional theory (DFT) calculations.
一种新型的扩展四苯基乙烯（TPE）-碳硼烷-TPE 五聚体已被合成，方法是使用两个相邻的碳硼烷部分作为中心桥，并在侧位使用三个 TPE 单元。通过增加碳硼烷和 TPE 之间的桥接数量，其固态荧光量子产率大大提高到 68.2%。随后，发射颜色从蓝色变为橙黄色（126nm）。通过密度泛函理论（DFT）计算，对扩展的 TPE-碳硼烷-TPE 五聚体的电子结构进行了机械分析。
