초록

본 연구는 유기발광다이오드(OLED)용 적색형광 물질인 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM)유도체들의 합성에 관한 것으로서, 유도체들은 Knoevenagel 축합반응에 의하여 합성되었다. 이들은 전자공여성의 아미노스티릴기와 전자흡인성의 시아노(니트릴)기의 공액구조를 가지고 있다. 합성한 물질은 각각 FT-IR, $^1H-NMR$ 등을 통하여 그 구조적 특성을 확인하였고, 융점, 수득율 등을 통하여 열적 안정성, 반응성 등을 확인하였으며, UV-visible과 PL분석으로부터 이 형광재료들의 광학적 특성을 확인하였다.

4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) derivatives were synthesized by Knoevenagel condensation. They are red-emitting materials for OLED (Organic Light-Emitting Diode) composed of electron donor of aminostyryl groups and electron acceptor of two cyano(nitrile)groups in a conjugated structure. The structural properties of reaction products were analyzed by FT-IR and $^1H-NMR$ spectroscopy. The thermal stabilities and reactivities were measured by melting points and yields. The UV-visible and PL properties can be determined by exitation and emission spectra, respectively.
