Abstract
The new hexasubstitue-cyclophosphazene compounds containing chalcone derivatives (2-11) were obtained from the reactions of hexachlorocyclotriphosphazene (1) with several hydroxy chalcones in K 2CO3/acetone system. All products were generally obtained in high yields. The structures of the compounds were defined by elemental analysis, FT-IR, 1H, 13C and 31P NMR spectroscopy. Dielectric measurements for phosphazenes containing chalcone compounds (5-8) were carried out by means of an impedance analyzer as a function of temperature and frequency. Dielectric properties of samples prepared in a plate form were measured at room temperature over the frequency range 50 Hz to 2 kHz and given as compared with each other. © 2014 Elsevier Ltd.
