METHOD FOR FORMING FLUORESCENT THIN FILMS BASED ON MIXED SUBSTITUTED PHTALOCYANINE DERIVATIVE Russian patent published in 2023 - IPC C09K11/06 C07D487/22 C07F5/00 C07F3/06 C07F1/08 

FIELD: manufacturing of thin films.

SUBSTANCE: invention relates to methods for creating materials for sensor devices, namely to a method for forming fluorescent thin films based on phthalocyanine derivatives. The method consists of formation of Langmuir layers from a solution of a phthalocyanine derivative in an organic solvent. In order to obtain ordered films of phthalocyanine derivatives exhibiting the fluorescence effect, mixed-substituted phthalocyanine derivatives with alkoxy and chloro substituents or their complexes with holmium, zinc, or copper, which exhibit the properties of electron donors or acceptors, are used. Ordered films of phthalocyanine derivatives are obtained by transferring layers from the water surface to substrates using the Langmuir-Schaefer method at a compression rate of 15-45 cm²/min, a surface pressure of 0-0.2 mN/m and a temperature of 293-295 K.

EFFECT: invention makes it possible to obtain a thin-film material, which can be used as a functional and/or structural material in the production technology of various sensor devices.
