- Abstract
- 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.
