Electronic coupling between the porphyrin units of a laterally-bridged dimanganese(III) bis-porphyrin 2 is explored using electrochemistry, spectroelectrochemistry and resonance-Raman spectroscopy. It is found that strong electronic interactions between the manganese(III) ion and the porphyrin macrocycle enhance the perturbations experienced by these bis-porphyrin systems when compared to related monomer porphyrin systems. In turn this leads to effective electronic communication between the manganese ions in the bis-porphyrin. This finding has importance in the design of molecular wires based on laterally-bridged oligo-metallo-porphyrins.
利用电化学、光谱电化学和共振拉曼光谱研究了横向桥联双锰（III）双卟啉2的卟啉单元之间的电子耦合。研究发现，与相关的单体卟啉体系相比，锰（III）离子与卟啉大环之间的强电子相互作用增强了这些双卟啉体系所经历的扰动。这进而导致双卟啉中锰离子之间的有效电子通信。这一发现对于基于横向桥联低聚金属卟啉的分子导线设计具有重要意义。
