Enhancing the low-energy absorption band and charge mobility of antiaromatic Ni^II norcorroles by their substituent effects
Access this Article
Dissymmetrical substitution of norcorrole enables the preparation of various norcorrole derivatives as air- and moisture-stable species. Intramolecular charge transfer interactions between electron-donating substituents and the norcorrole core in these norcorroles significantly enhanced their low-energy absorption bands, which were forbidden in symmetrical NiII dimesitylnorcorrole.
