An Influence of Copper Cation in the Complex on Structure of the Nanostructured Layers, Spectral and Electrocatalytic Characteristics of Langmuir-Schaeffer Films of Triphenylcorrole

Abstract

An influence of copper cation in the complex on structure and properties of the floating layers of 5,10,15-triphenylcorrole (Cu[(ms-Ph) 3 Cor]) at the air-water interface was studied. The structure of the layers has been determined using the method of quantitative analysis of compression isotherms. A model of stable nanostructured layers of the substance has been constructed. Copper cation in the macrocycle increases the density of two-dimensional M-nanoaggregates, while the number of molecules in such aggregates experiences 2-3-fold growth. Like the metal-free triphenylcorrole, this copper-containing compound in multilayer Langmuir-Schaeffer (LS) films with edge-on arrangement of molecules forms aggregates with strong intermolecular interactions. Such LS films may be suitable for electrocatalysis in the oxygen reduction reaction.
