Magneto-chiral dichroism (MChD) is an interesting phenomenon in which the absorbance of a chiral molecule depends on the direction of the magnetic field. As the MChD of two enantiomers is opposite in nature, MChD has received considerable attention for the development of magneto-optical devices and new asymmetric synthetic methods, as well as being an explanation for the origin of the homochirality of life. In this perspective, the theoretical background behind MChD is introduced, and then, the first examples of metal complexes and aromatic π-conjugated systems are discussed. Furthermore, the electronic properties of aromatic π-conjugated systems, such as orbital angular momentum and exciton chirality, are theoretically explained, and the possibility of MChD-based photoresolutions is described.

有机化合物的磁-手性二色性研究的最新进展。

磁-手性二色性（MChD）是一种有趣的现象，其中手性分子的吸光度取决于磁场的方向。由于两种对映异构体的MChD本质上是相反的，因此MChD在磁光器件的开发和新的不对称合成方法方面得到了相当大的关注，并为生命的同质性提出了解释。从这个角度出发，介绍了MChD的理论背景，然后讨论了金属络合物和芳香族π共轭体系的第一个例子。此外，从理论上解释了芳香族π共轭体系的电子性质，例如轨道角动量和激子手性，并描述了基于MChD的光分辨率的可能性。
