Abstract

6-Alkyl-3-chromonealdehyde (2,2-dialkyl)hydrazone derivatives were synthesized by dehydration condensation. They are green-emitting materials for organic light emitting device (OLED) composed of electron acceptor of 6-alkyl-3-chromonealdehydes and electron donor of 2,2-dialkylhydrazones 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-visibles and PL properties were also determined by excitation spectra and emission spectra, respectively.

본 연구는 유기발광디바이스용(OLED) 녹색발광재료인 6-알킬-3-크로몬알데히드(2,2-디알킬)하이드라존 유도체의 합성에 관한 것으로서, 유도체들은 탈수축합반응으로 합성되었다. 이들은 전자흡인성의 6-알킬-3-크로몬알데히드류와 전자공여성의 2,2-디알킬하이드라존류의 공액구조를 가지고 있다. 합성된 물질들은 각각 FT-IR, $^1H$-NMR 스펙트럼으로부터 그의 구조적 특성을 확인하였고, 융점, 수득률에 의하여 열적 안정성, 반응성을 확인하였으며, 여기스펙트럼과 발광스펙트럼으로부터 자외가시광과 발광특성을 확인하였다.
