研究了噻吩醌类化合物在有机光化学中的单重态裂变。化合物的噻吩醌长度的增加实现了用于单线态裂变的合适的堆积结构和能级。的光电流和设备的外部量子效率的磁场依赖性揭示了单线态裂变的化合物和三重态激子解离成电荷。
Singlet fission of thienoquinoid compounds in organic photovoltaics is demonstrated. The escalation of the thienoquinoid length of the compounds realizes a suitable packing structure and energy levels for singlet fission. The magnetic-field dependence of the photo-current and the external quantum efficiency of the devices reveal singlet fission of the compounds and dissociation of triplet excitons into charges.
