Three anthracen- or pyrene-based coumarin derivatives have been successfully synthesized and characterized by EA, IR and 1H NMR. The photophysical properties of all derivatives were investigated by UV-Vis and photoluminescence spectroscopic analysis. Their thermal stabilities were demonstrated by TGA. These compounds exhibit strong blue mission under ultraviolet light excitation and have potential
已成功合成了三种基于蒽或pyr的香豆素衍生物,并通过EA,IR和1 H NMR对其进行了表征。通过UV-Vis和光致发光光谱分析研究了所有衍生物的光物理性质。TGA证明了它们的热稳定性。这些化合物在紫外光激发下表现出强烈的蓝色使命,并有可能探索有机电致发光材料。制备具有ITO / TAPC(20 nm)/ TBADN的真空处理的掺杂器件:b1(x wt%,30 nm)/ TPBi(50 nm)/ Liq(2 nm)/ Al(150 nm),其中基于b1的器件表现出最佳的电致发光性能,最大亮度为8165 cd / m 2 最大发光效率为6.13 cd / A,最大外部量子效率(EQE)为2.75%。
