| Abstract: | Multi-layered organic thin films were prepared by stepwise vapor deposition of planar molecules with delocalized π-electrons on indium tin oxide (ITO) glass or KCl crystalline surface. The order of the deposition of π-planar molecules with different redox potential can control enhancement or inhibition of the hole or electron transfer according to the concept of “sequential potential field”, or a potential cascade by the organization of redox components. This concept is here applied to electrochromic or electroluminescent devices composed of multi-layered organic thin films. |
