"This work aimed to obtain stable nanostructured floating monolayers and thin films of tetraphenylporphin (H2TPP) by the Langmuir-Schaefer (LS) method. The layer structure was analyzed within the framework of the model of a nanostructured M-monolayer using a quantitative method for analyzing compression isotherms [1-4]. The obtained LS films were examined by electron absorption spectroscopy (Fig. 1a) and electron microscopy (SEM) (Fig. 1b). \r\n (a) (b)\r\n \r\n\r\n\r\nFig. 1. (a) UV-vis spectra of a solution of H2TPP in CH2Cl2 (red) and its LS-films (49 layers, black). On the UV-vis insert, the spectra of films of various thicknesses (2-49 layers); (b) SEM image of LS-film H2TPP.\r\nIt was found that H2TPP at the water-air interface at different initial degrees of surface coverage (cface) forms nanostructured edge-on monolayers. The main characteristics of the layers are determined. It was shown that H2TPP forms two-dimensional nanostructures of a very large size - about 60 nm in diameter. In LS-films, these nanostructures are combined into even larger ones - the average diameter is about 250 nm (Fig. 1b). The spectra of Н2ТРР LS films are characterized by a strong bathochromic shift of the Soret band (by 21 nm) and Q-bands (by 4-6 nm) relative to the spectrum of the solution (Fig. 1a), which indicates the formation of J-type nanoaggregates."^^ .
