The goal of this work is to study the processes of self-organization in tetraphenylporphyrin (H2TPP) films made by condensation under various conditions. Experimental studies of the spectral characteristics of H2TPP thin films obtained by the liquid method from a H2TPP toluene solution and by vacuum deposition on different substrates are carried out. It is shown that the structure of the H2TPP samples changes depending on the technique of synthesis on different substrates, which shows itself in changes (“red” shift) in the photoluminescence and absorption spectra. The changes are caused by a different degree of crystallinity depending on the homogeneity of the surface of the substrates and their temperature.
