碗状芳香族硼亚酞菁与反[2.2]对环钯的连接首次观察到了凸面和凹面之间的电子通讯。合成了三种反[2，2](1，4)亚酞菁的异构体，根据亚酞菁单元的取向分别为凹-凹(CC)、凸-凹(CV)和凸-凸(VV)，并用~1H 核磁共振、电子吸收、荧光、磁圆二色谱和X-射线结晶学结合分子轨道计算对其进行了表征。从CC型到CV型，再到V型，由于共轭体系的空间扩展，Q- 带变宽并最终分裂，理论上也得到了复制。
The connection of bowl‐shaped aromatic boron subphthalocyanines withanti‐[2.2]paracyclophane resulted in the first observation of electronic communication between convex and concave surfaces. Three isomers ofanti‐[2.2](1,4)subphthalocyaninophane, described as concave–concave (CC), convex–concave (CV), and convex–convex (VV) according to the orientation of the subphthalocyanine units, were synthesized and characterized by various spectroscopic techniques, including1H NMR, electronic absorption, fluorescence, and magnetic circular dichroism spectroscopy and X‐ray crystallography, together with molecular‐orbital calculations. On going from theCCsystem toCVand further toVV, the Q band broadened and finally split as a result of through‐space expansion of the conjugated systems, which were also reproduced theoretically.
