Pyrimidine유도체의 2번 위치의 변경을 통한 진청색 OLED TADF 발광 재료 합성 및 평가

다국어 초록 (Multilingual Abstract)

For the blue-blue TADF material used for the OLED device emissive layer, 5,5',5''-(pyrimidine-2,4,6-triyltris(benzene-2,1-diyl))tris(5H-benzofuro[3,2-c]carbazole) [TBFCz-Pym] and 5,5',5''-(pyrimidine-2,4,6-triyltris (benzene-2,1-diyl))tris(7,7-dimethyl-5,7-dihydroindeno[2,1-b]carbazol e) [TICz-Pym] based on pyrimidine derivatives were designed and synthesized. Pyrimidine was set as the core, the donor groups 5H-benzofuro [3,2-c]carbazole [BFCz] and 7,7-dimethyl-5,7-dihydroindeno[2,1-b] carbazole [DMICz] were set as shells, and optical properties and device evaluation were performed on the synthesized materials. We confirmed the possibility of changing the donor group in the core-shell structure TCz-Pym to control the quantum efficiency, the emission wavelength and the half width of the emission spectrum.
