초록

유기전기발광 소자에서 천연색을 구현하기 위해서는 적색, 녹색, 청색 발광물질이 필요하다. 그러나 적색과 녹색의 발광 물질에 대한 연구는 매우 활발하나 청색의 물질에 대한 연구가 미흡한 것은 높은 발광 에너지 때문으로 보인다. 본 연구는 발광 효율이 높으며 열적 안정성이 좋은 화합물을 합성하려는 것으로 carbazole로 치환된 anthracene 화합물 합성에 관한 것이다. Tert-butyl 기로 치환된 carbazole에 전기 발광 성질과 열적 안정도가 좋은 anthracene을 직접 결합시킴으로써 정공전달 특성을 갖는 작용기와 전자전달 특성을 갖는 작용기 간의 거리에 대한 연구를 시작하고자 하였다.

In order to express the natural color in organic light emitting diode(OLED), red, green, and blue luminescent materials are needed. While lots of red and green emitters are searched actively, not many useful blue emitters are found yet. It is due to the high energy gap for the blue emission. This research is about a synthesis of the blue emitting compound with high emission efficiency and thermal stability, which starts with carbazole and anthracene. Carbazole with bulky substituent, tert-butyl group, is connected directly to electroluminescent and thermally stable anthracene. The distance between the hole transporting group and the electron transporting group are studied for the relevance to the luminescence.
