초록

본 연구는 유기발광 디바이스용(Organic Light Emitting Device, OLED) 녹색 발광재료인 3-크로몬알데히드 유도체의 합성에 관한 것으로서, 유도체들은 탈수 축합반응으로 합성되었다. 이들은 전자흡인성의 3-크로몬알데히드류와 전자공여성의 디아민류의 공액구조를 가지고 있다. 합성한 물질들은 각각 FT-IR, 1H-NMR 스펙트럼으로부터 그의 구조적 특성을 확인하였고, 융점, 수득률 등을 통하여 열적 안정성, 반응성들을 확인하였으며, 여기스펙트럼과 발광스펙트럼으로부터 자외가시광과 발광특성을 확인하였다.

We study on the preparation of green emitting materials for organic light emitting device. 3-chromonealdehyde derivatives possessing a conjugated structure, which were composed of electron acceptor of 3-chromonealdehydes and electron donor of diamines, were synthesized by dehydration-condensation process. 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 excitation spectra and emission spectra, respectively.

Keywords:3-chromonealdehyde derivatives;organic light emitting devices;dehydration-condensation
