ABSTRACT
I. INTRODUCTION In 1985 we demonstrated that micelles formed by cationic surfactants with a ferrocenyl group can be broken into monomers when the surfactants are oxidized chemically or electrochemically and that a solubilizate is released from the micelles as the micelles dissociate [1,2]. This phenomenon was then applied to the electrochemical formation of organic thin films using the same surfactants [3,4]. Later, we illustrated the preparation of organic pigment thin films by this method using nonionic ferrocenyl surfactants (FPEG) [5-7]. These later studies showed that the organic pigment particles are not actually dissolved in the micelles formed by the surfactants but are dispersed by having the surfactants adsorbed onto the particle surface. The pigment particles are destabilized when the surfactants adsorbed on the particles are oxidized, and finally the particles deposit on the electrode (Fig. 1). This method has the following advantages:
1. Thin films of a wide variety of organic compounds that are soluble in micellar solutions and dispersible in surfactant solutions may be prepared.
