• where the emissive layer also contained an inorganic salt and a conducting polymer. Recently, a step-change in device performance were achieved by He et al. who employed a cationic TADF compound that possesses low-lying through-space and through-bond charge transfer excited states [23]. The LEEC showed

Electrooxidative polymerization led to the corresponding poly(heterotriacene)s P2–P4. Keywords: conducting polymer; C–S coupling; C–Se coupling

• properties. These properties allow their use in several electronic devices [1][2]. The poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the most conducting and stable (thermal and chemical) conducting polymer. For these reasons PEDOT thin films have been extensively studied [3]. Special attention has been
