Micelle ferrocenyl

A somewhat different micelle-disruption method was used to prepare thin reactive films on electrode surfaces. For this purpose, micelles containing ferrocenyl surfactant 9 and a dissolved dye, e.g. phthalocyanine or quinone, were electrolyzed. The ferrocenyl micelles broke up into monomers whenever the iron atoms were oxidized electrochemically. The dissolved dyes then precipitated as transparent nanometre films onto the electrode surface. ...

Photo-oxidation of ferrocene by CCI4 in solution can normally only be effected by u.v. irradiation. However it has been observed that the reaction may be carried out with visible light in cetyltrimethylammonium chloride micelles, albeit with low quantum yield.It is suggested that the main effect of micellization may be an increase in the oxidation potential of ferrocene or alternatively that a CTTS state of ferrocene is involved under these conditions. The ring substitution of ruthenocene by irradiation in 1 1 (v/v) solutions of ethanol with CCI4, CHCI3, or CH2CI2 proceeds by a mechanism similar to that previously found for ferrocene. Other reports consider the synthesis of ferrocenyl thioesters and the photooxidation of ferrocene. ...
