Herein, we present a new class of singlet fission (SF) materials based on diradicaloids of carbene scaffolds, namely cyclic (alkyl)(amino)carbenes (CAACs). Our modular approach allows the tuning of two key SF criteria: the steric factor and the diradical character. In turn, we modified the energy landscapes of excited states in a systematic manner to accommodate the needs for SF. We report the first example of intermolecular SF in solution by dimer self‐assembly at cryogenic temperatures.

卡宾衍生的双基类化合物中的单重态裂变

在本文中,我们基于卡宾支架的双基类化合物,即环状(烷基)(氨基)卡宾(CAAC),提出了一种新型的单峰裂变(SF)材料。我们的模块化方法允许调整两个关键的SF标准:空间系数和双自由基特征。反过来,我们以系统的方式修改了激发态的能量分布,以适应SF的需求。我们报道了在低温下通过二聚体自组装在溶液中形成分子间SF的第一个例子。
