Abstract

The aim of the work was to prepare the films on base of β-diketophosphazene and amines and to study their properties. The diketo-function-containing aryloxycyclotriphosphazene was synthesized by reaction of hexakis(4-chloromethylphenoxy)cyclotriphosphazene with sodium acetylacetonate. It has been established that the optimal solvent for this reaction is dimethylformamide. The chemical structure of the synthesized diketophosphazene was characterized by Fourier transform infrared spectroscopy (FTIR), 1H, 13C and 31P nuclear magnetic resonance (NMR) and MALDI-TOF mass-spectrometry. The synthesized diketophosphazene was used to obtain polymers, which were characterized by infrared spectroscopy. In addition, all these polymers were used for films preparing, which were tested for hydrophobicity, heat resistance (TGA) and adhesion to glass. It was found that the obtained film, which were made using diketophosphazene and α,ω-bis(3-aminopropyl)oligodimethylsiloxane, demonstrates the best operational properties. This film is quite flexible, its decomposition temperature is 320 °C, adhesion value to glass is 1 by ISO 2409: 2007, and the contact angle is 101°. The obtained films can be used in the form of metal complexes in the OLED technology.
