Photoinitiated mediated transport of H3O+ and/or OH- across glycerol monooleate bilayers doped with magnesium octaethylporphyrin.

Photogenerated magnesium octaethylporphyrin cation in glycerol monooleate bilayers is shown to mediate the transport of H3O+ and/or OH-. Data from voltage clamp and open-circuit experiments are consistent with the classic Markin or Laüger carrier model. Photoinitiated currents exhibit the expected transient and steady-state behavior.
