title: Singlet biradical character of phenalenyl-based Kekulé hydrocarbon with naphthoquinoid structure.
abstract: [reaction: see text] A new Kekulé polycyclic hydrocarbon with a singlet biradical index of 50% was synthesized. The singlet biradical character was assessed with UV and 1H-NMR spectroscopy, cyclic voltammetry, SQUID magnetic susceptibility measurement, and quantum chemical calculations.
