Herein, we report the selective synthesis, characterization, and photophysical properties of two novel chiral carbon macrocycles. Non-planar ()-2,2'-bis(methoxymethoxy)-1,1'-binaphthalene was introduced into the scaffold of oligo-paraphenylenes to achieve the chirality in these macrocycles. Their photophysical properties were investigated by steady-state and time-resolved spectroscopies, as well as circular dichroism and circularly polarized luminescence spectroscopies. We demonstrate that the emission maxima of the chiral macrocycles are redshifted compared to chiral binaphthyl units and that macrocycles show chiroptical properties (|| > 1.0 × 10).
在此，我们报告了两种新型手性碳大环化合物的选择性合成、表征及光物理性质。将非平面的（）-2,2'-双（甲氧基甲氧基）-1,1'-联萘引入到低聚对亚苯基骨架中，以实现这些大环化合物的手性。通过稳态和时间分辨光谱以及圆二色光谱和圆偏振发光光谱对它们的光物理性质进行了研究。我们证明，与手性联萘单元相比，手性大环化合物的发射最大值发生红移，并且大环化合物表现出旋光性质（|| > 1.0 × 10）。
