초록
본 연구는 유기발광디바이스용 적색형광물질인 6-(10-알킬페노티아진-3-비닐렌)-2-메틸-4-디시아노메틸렌-4H-피란 합성에 관한 것으로서 유도체들은 Knoevenagel 축합반응에 의하여 합성되었다. 이들은 전자공여성의 6-(10-알킬페노티아진-3-비닐렌)기와 전자흡인성의 2-메틸-4-디시아노메틸렌-4H-피란의 공액구조를 가지고 있다. 합성한 물질은 각각 FT-IR, 1H-NMR등을 통하여 그의 구조적 특성을 확인하였고, 융점, 수득율을 통하여 열적 안정성, 반응성 등을 확인하였으며, UV-visible과 PL분석으로부터 이 형광재료들의 광학적 특성을 확인하였다.
6-(10-Alkylphenothiazine-3-vinylene)-2-methyl-4-dicyanomethylene-4H-pyran derivatives were synthesized by Knoevenagel condensation. They are red-emitting materials for organic light emitting device (OLED) which composed of electron donor of 6-(10-Alkylphenothiazine-3-vinylene) groups and electron acceptor of -2-methyl-4-dicyanomethylene-4H-pyran groups by a conjugated structure. The structural properties of reaction products were analyzed FT-IR and 1H-NMR spectroscopy. The thermal stabilities and reactivities were measured by melting points and yields. The UV-visibles and PL properties can be determined by exitation spectra and emission spectra, respectively.
