摘要

利用金模板法合成了结构高度受限的环状蒽醌二甲烷（AQD）二聚体。X 射线衍射分析和紫外可见光谱分析显示，蒽醌二甲烷骨架采用了深度折叠结构，与非环化单体蒽醌二甲烷相比，二聚体中的蒽醌二甲烷具有红移吸收。由于具有刚性和约束结构，具有平面手性的环状 AQD 二聚体的两种对映体都可以分离出来，并显示出强烈的圆二色性信号。该研究表明，以金为模板的方法是获得具有 AQD 骨架的高约束环状结构的重要途径。

Synthesis and Chiroptical Properties of Cyclic Anthraquinodimethane Dimer Using Au-Templated Method

Cyclic anthraquinodimethane (AQD) dimer with a highly constrained structure was synthesized by using the Au-templated method. X-ray diffraction analysis and UV-Vis spectroscopy revealed that the AQD skeleton adopts a deeply folded structure and exhibits red-shifted absorptions in the dimer compared to those in non-cyclized monomeric AQD. Due to the rigid and constrained structure, both enantiomers of the cyclic AQD dimer with planar chirality can be isolated and show strong circular dichroism signals. It is demonstrated that the Au-templated method is a valuable way to access a highly constrained cyclic structure with AQD skeletons.
