Web1 Introduction. π-Conjugated polycyclic hydrocarbons (PHs) can either accommodate π-electrons in the bonding orbitals to form a closed-shell ground state or show open-shell ground state due to the existence of one or more unpaired electrons [ 1 ]. Monoradical PH is comprised of an unpaired electron in neutral molecule in the ground state [ 2 ].
