PHOTOEFFECTS OF PIGMENTED LIPID MEMBRANES IN A MICROPOROUS FILTER

Academic Article

Abstract

  • Abstract. The light‐induced voltage and current generated by pigmented lipid membranes have been investigated. The membranes, separating two aqueous solutions, were formed in microporous filters with pore sizes ranging from 0.05 to 8μm in diameter and densities of 105 to 6 × 108 pores/cm2. The structure and some physicochemical properties of these membranes are described and compared with those of planar BLMs. Photopotentials up to 400 mV could be developed across these membranes having an effective current of 21μA‐cm‐2. These and other parameters (redox couples and lifetime) were studied over a period of days. The advantages of this membrane system such as long‐term stability and manipulability are discussed.
