Research Papers : Synthesis of Green Emitting Materials for OLED

Pyung Jin Chung

Abstract

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 1 H-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.

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, 1 H-NMR 스펙트럼으로부터 그의 구조적 특성을 확인하였고, 융점, 수득률 등을 통하여 열적 안정성, 반응성들을 확인하였으며, 여기스펙트럼과 발광스펙트럼으로부터 자외가시광과 발광특성을 확인하였다.
