Popis:	A series of new electrochromic derivatives of 3-aryl-4,5-bis(pyridin-4-yl)isoxazole was synthesized. Their electrochemical characteristics were studied by cyclic voltammetry, and a low eff ect of the substituents in the isoxazole and pyridinium cycles on the positions of the oxidation and reduction peaks was shown. The electrochromic cells prepared on the basis of the synthesized compounds were reversibly colored into brown upon the application of a voltage of 1.5 V. The spectral properties of the synthesized compounds under the electric field application and their stability for cycling from 0 to 2 V were studied.
