摘要：

Mixed Langmuir-Blodgett films comprised of various relative concentrations of silver tetraneopentoxyphthalocyanine (AgTNPc) and stearic acid are reported. Electronic spectroscopic polarization data are discussed in terms of the relative orientation of aggregated AgTNPc domains in the film. Electrochemical data confirm the oxidation of Ag(II)TNPc(-2) successively to [Ag(III)TNPc(-2)]+ and [Ag(III)TNPc(-1)]2+ in the film phase without loss of orientation. The film was also subject to chemical oxidation and reduction, and the degree of organization following such chemistry is discussed. Ag(II)TNPc(-2) aggregates, even when diluted with stearic acid, do not display resolved ESR spectra, but ternary film mixtures of Ag(II)TNPc(-2)/H2TNPc(-2)/stearic acid do exhibit such resolved spectra.
