Synthesis and Characterization of Carbazole Derivate for Blue light Emitting Material

카바졸을 포함하는 청색 OLED 재료의 합성

We designed and synthesized DFPCE blue emitting materials by Mc Murry coupling reaction in order to improve the device efficiency and stability. The structure was confirmed by $^1H$-NMR. The physical properties were characterized by differential scanning calorimetry, thermogravimetric analysis, UV-vis, photoluminescence spectrum and cyclic voltammetry. The decomposition temperature of the material, which correspond to a 5% weight loss upon heating, is $513.58^{\circ}C$. The photoluminescence (PL) spectrum of DFPCE exhibited blue emission at 425 nm in chloroform solution and 462 nm in film.
