Oxidation of [3]naphthylenes to cations and dications converts local paratropicity into global diatropicity by Abel Cárdenas, Zexin Jin, Yong Ni, Jishan Wu, Yan Xia, Francisco Javier Ramírez, Juan Casado

“…Oxidized states of polycyclic aromatic hydrocarbons are of importance as they represent charged conductive species in organic semiconductor substrates. In this work, we investigated the properties of radical cations and dications of linear and angular [3]naphthylenes, consisting of fused aromatic naphthalenoid and antiaromatic cyclobutadienoid moieties and containing different degrees of paratropicity. …”
