| Outline of Final Research Achievements |
Norcorrole is a ring-contracted antiaromatic porphyrin, which lacks two meso-carbons from regular porphyrin. We succeeded to prepare a tethered norcorrole dimer, which predominantly adopted a closely stacked structure in both solid and solution states. The antiaromaticity of the stacked norcorrole dimer was significantly reduced and the stability of the complex was enhanced. The aromatic/antiaromatic character of the stacked norcorrole was evaluated by 1H NMR analysis and theoretical calculations. We concluded that this phenomenon is likely originated from the emergence of three-dimensional aromaticity in the stacked antiaromatic π-systems.
