Aromaticity reversal in the lowest triplet state

■ Natural Sciences / Aromaticity reversal in the lowest triplet state A group of Yonsei researchers demonstrates that bis-rhodium hexaphyrins containing [26] and [28] π-electron peripheries show properties consistent with Baird’s rule As any organic chemist will tell you, aromaticity is a fundamental concept because it relates to the chemical properties and reactivities of a wide range of species. At the most basic level, a compound (more specifically, a planar ring molecule) can be classified as aromatic, antiaromatic, or non-aromatic. The quantum mechanical basis for this classification was described by Hückel, whose [4n+2] rule defined a compound as being aromatic when its number of π-electrons … Continue reading Aromaticity reversal in the lowest triplet stateRead More →
