Two voltammetric techniques, cyclic voltammetry ( CV ) and chronocoulometry ( CC ), were used to investigate the redox characteristics of an organic semiconductor, 2,2′,7,7′‐tetrakis(diphenylamino)‐9,9′‐spirobifluorene (spiro‐ TAD ). The electron‐transfer characteristics of spiro‐ TAD , including the formal oxidation potentials ( E o ′), diffusion coefficients ( D o ), and electron‐transfer rate constants ( k o ′), were estimated by a combination of CV and CC measurements. The energy of the highest‐occupied molecular‐orbital could also be found from the quantitative relationship between the oxidation potential and the ionization energy.
