Anotācija The organic light emitting diode (OLED) is a promising device for future technologies, like flat panel displays and novel light sources. So far the OLED struc-tures have mostly been made by thermal evaporation in vacuum. An alternative approach is to use small molecules which form solid state with glassy structure from solutions. Such compounds can be used in the ink-jet printing technologies and result in reducing the OLED prices. In this paper, we present an original red fluorescent organic compound 2-(2-(4-(bis(2-(trityloxy)ethyl)amino)styryl)-6-methyl-4H-pyran-4-ylidene)-1H-indene-1,3(2H)-dione (ZWK1), with the maximum of the photoluminescence spectrum for solid state at 657 nm. The structure of the electroluminescent device was ITO/PEDOT: PSS (40 nm)/ZWK1 (120 nm)/LiF (1 nm)/Al (100 nm). The electroluminescence spectra correspond to the CIE coordinates x = 0.65 and y = 0.34 with the maximum at 667 nm. The power and luminance efficiency at the luminance of 100 cd/m2 is 0.43 lm/W and 1.97 cd/A, respectively.
