  Photochemical Regulation of the Electrical Properties of the Novel Planar Bilayer Lipid Membrane Incorporating Spiropyran Derivatives

  摘要：

  We incorporated the alkyl chain substituted spiropyran derivatives, 1-methyl-3,3-dimethyl-6'-nitrospiro[indoline-2,2'-[2H][1]benzopyran] (SP1), 1-octadecyl-3,3-dimethyl-6'-nitrospiro[indoline-2,2'-[2H][1]benzopyran] (SP18), and 1-octadecyl-3,3-dimethyl-6'-nitro-8-[docosanoyloxymethyl]spiro[indoline-2,2'-[2H][1]benzopyran] (SP1822) into the planar bilayer lipid membranes (BLM) of soybean lecithin for the first time, and the photoresponse of the BLM was monitored. When a dc voltage was applied across the BLM, the transmembrane current changed under alternate irradiation with ultraviolet light and visible light. Such a photoelectric response of the BLM seems to be caused by the change in the membrane conductivity due to photoisomerization of spiropyran.
