| dc.description.abstract | A series of phosphorescent mesogenic copolymers with various feed ratios of iridium-coordinating monomer as a side group have been prepared. Structure and composition of copolymers were confirmed by Fourier-transform infrared (FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. Molecular weight of copolymers was determined to be in the range of 7 to 73 kDa by GPC measurement. UV-Vis absorption and photo- and electroluminescence properties of copolymers were investigated. As a result, copolymer IrCP-1 containing 1 mol% iridium-coordinating comonomer showed the highest luminance and current density. Copolymer IrCP-3 with 5 mol% iridium-coordinating comonomer exhibited a satisfactory dichroic ratio of 1.47. | - |
| dc.description.abstract | 인광성 메소제닉 공중합체의 이색성을 평가하기 위하여 이리듐이 배위된 치환체를 곁사슬에 갖는 폴리플루오렌 공중합체를 합성하였다. 이때 벤조치아디아졸, 디옥틸플루오렌 및 이리듐착물-치환 플루오렌의 조성비를 1, 2, 5, 8, 11, 25 및 37.5 mol%로 변화시켰다. 합성한 공중합체의 구조 및 조성을 Fourier-transform infrared (FTIR) 및 proton nuclear magnetic resonance (1H NMR) 분광분석법으로 조사하였다. 또한 공중합체의 UV-Vis 흡수, 광발광및 전기발광 특성을 조사하였다. 공중합체의 분자량은 GPC 측정에 의해 7 내지 73 kDa 범위로 결정되었다. 결과적으로 배향된 이리듐착물-치환 플루오렌 구조를 1 mol% 및 5 mol%로 갖는 공중합체를 각각 적용한 전기발광 소자가 각각 가장 높은 휘도 및 가장 뚜렷한 이색성비(1.47)를 나타내었다. | - |
