  1. aWavelength of absorption maximum.
  2. bTime for swiching color.
  3. cTime for beaching color.
  4. dOptical density (ΔOD) = lg[Tbleached/Tcolored], where Tcolored is the maximum transmittance in the oxidized state and that of Tbleached is in the neutral state.
  5. eQd is ejected charge.
  6. fColoration efficiency (CE) η = ΔOD/Qd.
