Synthesis and electron-transport properties of a stable antiaromatic NiII norcorrole with the smallest meso-substituent

Abstract

meso-Dimethylnorcorrole Ni^II complex exhibited enough stability under ambient conditions despite the distinct antiaromaticity. The small methyl substituents realized a dense and long-range π-stacking in its solid state, which resulted in the superior electron-transporting ability to previously reported Ni^II norcorroles.
