Extension of the Clar’s Aromatic Sextet Rule to the singlet biradicaloids!
In a recent Article published in JACS (Link), A/P Wu Jishan and his local/international collaborators demonstrated that Clar’s Aromatic Sextet Rule can be further extended from the closed-shell polycyclic aromatic hydrocarbons to the open-shell polycyclic hydrocarbon systems, and provides an important guideline for the design of singlet biradicaloids with tailored biradical character and tunable optical, electronic and magnetic properties.
