초록
본 연구는 유기발광디바이스(OLED)용 적색형광물질인 N-알킬카르바졸-3-비닐렌-2-메틸-4-디시아노메틸렌-4H-피란의 합성에 관한 것으로서 유도체들은 탈수축합, SN2, Vilsmeier, 그리고 Knoevenagel축합반응에 의하여 합성되었다. 이들은 전자공여성의 N-알킬카르바졸-3-비닐렌기와 전자흡인성의 2-메틸-4-디시아노메틸렌-4H-피란의 공액구조를 가지고 있다. 합성한 물질은 각각 FT-IR, 1H-NMR 등을 통하여 그의 구조적 특성을 확인하였고, 융점, 수득률을 통하여 열적 안정성, 반응성 등을 확인하였으며, 여기 발광스펙트럼으로부터 이 형광재료들의 광학적 특성을 확인하였다.
N-Alkylcarbazole-3-vinylene-2-methyl-4-dicyanomethylene-4H-pyran derivatives were synthesized by dehydration, SN2, Vilsmeier, and Knoevenagel condensation. They are red-emitting materials for organic light emitting device (OLED) composed of electron donor of N-alkylcabazole-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.
