The template synthesis is used to produce powders and films based on naphthalocyanines and the corresponding metal complexes (Pc, CuPc, and NiPc). The atomic force microscopy (AFM) and X ray phase analysis (XPA) are employed in the study of structure and phase of fine powders and nanostructured films. The AFM data are used to determine the orientation and density of primary particles packed in the film. The XPA method is used to study the chemical composition and crystal structure of the synthesized samples. The regularities related to the structural features that affect the electrophysical properties of the films under study are revealed.

“…The first drift space, from the sample to the ion source of the mass spectrometer, the particles travel in a neutral state and are distributed according to the initial kinetic energies. The particles ionized in the ion source are pushed into the second drift space, in which they are already mass separation (m/z) [6].…”

“…Under the action of laser radiation, fragmentation of organic films and desorption of fragments from the surface occur [4]. The mass spectra of the desorbed fragments contain information on the molecular composition of the samples under study [5]. The aim of the work is to study the effect of laser radiation on the morphology of copper phthalocyanine thin films (CuPc and CuPcF16) and to investigate the possible fragmentation of organic molecules…”

The paper presents the results of mass spectrometric studies of laser-stimulated desorption from the surface of thin films based on organic copper phthalocyanine molecules with peripheral substituents on gallium arsenide substrates. Thin films (30-80 nm) of copper phthalocyanine with peripheral substituents in this regard are studied for the first time. The composition of particles desorbed from the surface of CuPc and CuPcF16 films by laser radiation of various wavelengths of 532 nm and 1.06 μm with a pulse duration of 10 ns was studied. The identification of the main fragments of molecules present in the desorption stream was carried out. It was shown that under the action of laser radiation, the surface is leveled and the films are fragmented, followed by desorption of molecular fragments.

“…From the literature it is known that the relaxation in organic molecular crystals mainly occurs with subsequent dissipation of excitation energy in the form of nonradiative transitions and can be realized ultimately in chemical reactions or decomposition reaction of phthalocyanine macrocycle The decay products are contained in the total desorption flow caused by the laser pulse. The study of laser-stimulated desorption from the surface of the irradiated films of MPc was carried out in a vacuum (10 -7 Pa) on the [2]…”

The study of MPc is motivated by the prospects of the creation of optoelectronic devices that operate in the visible light range. The combination of their physico-chemical and semiconducting properties makes them the promising material for cheap thermo-stable organic optoelectronic devices. In connection with this the question of degradation of macrocyclic phthalocyanine when exposed by harsh environments, in particular laser radiation, is very actual The studies of MPc's degradation under electron beam and pyrolysis is well Pyrolysis of polymeric cobalt phthalocyanine [ was carried out at 500 - 1000°C, the mass spectra were recorded across 0.6 - 3.6 minutes. The proposed mechanism of initial thermal degradation leads to the isoindole derivatives The paper presents results of a study of fragmentation of manganese phthalocyanine films that are in the condensed state on a solid surface by means of laser irradiation (λ=532 nm), i.e. in the spectral region of absorption
