안트라피라졸 화합물을 이용한 청색 유기전기발광물질의 합성과 특성에 관한 연구 = A study of synthesis and properties of Blue Organic Electroluminescent Materials which use the anthrapyrazole compound

다국어 초록 (Multilingual Abstract)

OLED(Organic Light Emitting Diode) has been very attractive due to the potential applications in flat panel displays. Also, OLED is being researched worldwide on account of their's low voltage drive, self-lighting, wide viewing angle and fast replying speed. Recently, electro-luminescent materials and devices are being developed for commercialization of OLED.
In this study, new blue emitting materials were designed and synthesized with anthrapyrazole compounds. They were characterized with 1H-NMR and FT-IR spectroscopy. Their thermal properties were analyzed with DSC and TGA. They were copolymerized with Styrene and MMA. It was found that all polymers have similar degradation temperature. However, the glass transition temperature of styrene copolymers showed clearly higher than those of methyl methacrylate copolymers. UV-vis and Spectroflurophotometer were used to investigate the optical characteristics. In the result, anthrapyrazole copolymers absorbed UV visible light ranging from 360 to 410 nm in THF. They showed the fluorescence in blue region ranging from 435 to 477 nm in THF and from 471 to 477 nm in film state.
