Spiro‐containing organic charge transport materials such as the one shown in the Figure are investigated by these authors. Based on detailed temperature and field‐dependent mobility studies it is shown that high mobility is preserved upon dimerization via the spiro center. Exceptional thermal stability of the amorphous state is also observed; this is normally only apparent in polymeric systems.
