Synthesis, Intermolecular Interaction, and Semiconductive Behavior of a Delocalized Singlet Biradical Hydrocarbon

Abstract

A phenalenyl-based Kekulé hydrocarbon with singlet biradical character has been isolated and characterized. Strong intra- and intermolecular interactions between the unpaired electrons lead to short π–π contacts and formation of one-dimensional chains (see picture). Thus, wide valence and conduction bands are established, and the compound shows semiconductive behavior.
