Abstract

original image

Teranthene—a molecular section of graphene: The surprising stability of teranthene at ambient conditions allowed its characterization, which pointed toward a high biradical contribution in the singlet ground state (see scheme). Polycyclic aromatic hydrocarbons with high singlet biradical character show high third-order nonlinear optical properties, which makes them interesting candidates for (opto)electronic devices.
