Abstract: Highlights • Charge transport mechanism in copolymer with thioxanthenone side groups is studied. • Thermal (Wt = 0.9 eV) and optical (Wopt = 1.8 eV) ionization trap energies were found. • Spectroelectrochemistry and electrophysics are verified independently the trap origin. Abstract The transverse charge transport mechanism in a specially synthesized novel methyl methacrylate copolymer containing 2 % electron-accepting 9H-thioxanthene-9-one side groups (poly(MMA-co-ThS)) has been studied experimentally and theoretically. These side groups are shown to be deep electron traps. The charge transport in poly(MMA-co-ThS) is governed by the model of phonon-assisted tunneling between traps. The optical ionization trap energy (Wopt = 1.8 eV), independently determined by a reduction spectroelectrochemical method, confirms the validity of the phonon-assisted tunneling model used to describe charge transport in organic dielectrics with high content of electron traps.
