Dimer formation of the N-confused porphyrin zinc(II), cadmium(II), and mercury(II) complexes was investigated experimentally as well as theoretically. The stable dimers were formed through coordination of the peripheral nitrogen atoms owing to flexible rotation of the confused pyrrole rings. The Z dimers were significantly more stable than the E dimers likely due to pi-pi interaction between the two
通过实验和理论研究了N混淆的卟啉锌(II),镉(II)和汞(II)配合物的二聚体形成。由于混淆的吡咯环的柔性旋转,通过周围氮原子的配位形成了稳定的二聚体。Z二聚体比E二聚体稳定得多,这可能是由于两个混淆的吡咯环之间的pi-pi相互作用所致。在内消旋未取代的衍生物的情况下,建议可能形成更高的低聚物,例如三聚体。
