Abstract:

Mixed Langmuir-blodgett films comprised of various relative concentration of silver tetraneopentoxyphthalocyanine AgTNPc and stearic acid are reported. Electronic spectroscopic polarisation data are discussed in terms of the relative orientation of aggregated AgTNPc domains in the film. Electrochemical data confirm the oxidation of AgIITNPc-2 successively to AgIIITNPc-2 and AgIIITNPc-12 in the film phase without loss of orientation. The film was also subject to chemical oxidation and reduction and the degree of organisation following such chemistry is discussed. AGIITNPc-2 aggregates, even when diluted following such chemistry is discussed. AgIITNPc- 2 aggregates, even when diluted with stearic acid, do not display resolved ESR spectra but ternary film mixtures of AgIITNPc-2H2TNPc-2stearic acid do exhibit such resolved spectra.
