Measured from chloroform solution at a concentration of 7.0×10⁻⁶ M.
Measured from thin films that were spin-coated from 5 mg/mL chloroform solution.
Cyclic voltammetry was performed with 0.1 M tetrabutylammonium hexafluorophosphate in dichloromethane.
Determined by differential scanning calorimetry at a temperature scan rate of 10°C/min.
