Abstract

The free base form of doubly meso-α linked N-confused porphyrin (NCP) tape 3 was successfully synthesized via Ir(I) mediated intramolecular coupling. The following silver complexation afforded the Ag(III) complex of doubly meso-α linked NCP tape 4. While 3 exhibited 38π aromatic characters, 4 exhibited not only 18π aromatic NCP-type characteristics but also a decent antiaromatic contribution of 12π pyrrolo[2,3-f]indole segment, as probed by NMR spectra, absorption spectra, and DFT calculations.

包含抗芳香族吡咯并[2,3-f]吲哚段的双介导α连接 N-共轭卟啉带银(III)络合物。

通过 Ir（I）介导的分子内偶联，成功合成了双介子-α连接的 N-混淆卟啉（NCP）带 3 的游离碱形式。随后进行银络合，得到了双介于α连接的 NCP 带 4 的 Ag（III）络合物。通过核磁共振光谱、吸收光谱和 DFT 计算，3 表现出 38π 芳香族特征，而 4 不仅表现出 18π 芳香族 NCP 型特征，而且 12π 吡咯并[2,3-f]吲哚片段也有相当的反芳香贡献。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
