Four new carbazole-based coumarin derivatives comprising a carbazole core and one or two coumarin chromophores, 7-(diethylamino)-3-(4-(9-(p-tolyl)-9H-carbazol-3-yl)phenyl)coumarin (Cz-Ph-C) and 3,3'-((9-(p-tolyl)-9H-carbazole-3,6-diyl)bis(4,4′-phenyl))bis(7- (diethylamino)coumarin) (Cz-2(Ph-C)), 7-(diethylamino)-3-(5-(9-(p-tolyl)-9H-carbazol-3- yl)thiophen-2-yl)coumarin (Cz-Th-C) and 3,3'-((9-(p-t
四种新的基于咔唑的香豆素衍生物,包括咔唑核和一个或两个香豆素生色团,7-(二乙氨基)-3-(4-(9-(对甲苯基)-9 H-咔唑-3-基)苯基)香豆素(Cz-Ph-C)和3,3'-((9-(对甲苯基)-9 H-咔唑-3,6-二基)双(4,4'-苯基))双(7-(二乙氨基) )香豆素)(Cz-2(Ph-C)),7-(二乙氨基)-3-(5-(9-(对甲苯基)-9H-咔唑-3-基)噻吩-2-基)香豆素(Cz-Th-C)和3,3'-((9-(对甲苯基)-9 H-咔唑-3,6-二基)双(噻吩-5,2-二基))双(7-(二乙氨基) )香豆素)(Cz-2(Th-C))已成功合成为有机发光器件的发光材料。系统地研究了这些化合物的光物理,电化学性质和热稳定性。结果表明,这些香豆素-咔唑杂化体在二氯甲烷溶液中表现出出色的热稳定性和高光致发光量子效率,并且发出强烈的绿色发射光。具有ITO / TAPC(20 nm)/
