The development of small organic CPL-active molecules with large luminescent dissymmetry factors is highly demanded due to their promising applications in chiroptical devices and sensors. This work describes the design and synthesis of a new family of CPL-active BF complexes, ()/()--, which were constructed by fusing a N̂O-chelated BF complex with [2.2]paracyclophane. These complexes display aggregation-amplified CPL with moderate dissymmetry factors values and moderate quantum yields both in solution and in the solid state. In addition, these photophysical properties were rationalized via X-ray diffraction and TD-DFT calculations.
由于具有大发光不对称因子的小有机圆偏振发光（CPL）活性分子在旋光器件和传感器中具有广阔的应用前景，因此对其需求极高。这项工作描述了一类新型CPL活性BF配合物（）/（）--的设计与合成，它们是通过将一个N̂O螯合的BF配合物与[2.2]对环芳烷融合构建而成。这些配合物在溶液和固态中均表现出具有中等不对称因子值和中等量子产率的聚集增强CPL。此外，通过X射线衍射和含时密度泛函理论（TD-DFT）计算对这些光物理性质进行了合理的解释。
