标题:与三(吡唑基)硼酸盐和三氟甲磺酸盐配体的深蓝色发光铈 (III) 配合物
摘要:红,绿,蓝三基色发光材料在照明和显示中非常重要.发红光的 Eu( Iii ) 配合物和发绿光的 Tb( Iii ) 配合物表现出高色纯度和光致发光 (Pl) 效率.然而,很难实现基于 F-F 跃迁的高效蓝光发射.或者,具有 D-F 跃迁的 Ce 3+可用于构建蓝色发光镧系元素配合物.在此,我们合成了两种基于氢化三(3-甲基吡唑基)硼酸盐(Tp Me )和氢化三(3,5-二甲基吡唑基)硼酸盐(Tp Me2 )的杂配ce( Iii )配合物ce-1Me-Otf和ce-2Me-Otf .) 配体,其中三氟甲磺酸酯用作辅助配体.Ce-1Me-Otf和ce-2Me-Otf在二氯甲烷中表现出强烈的蓝色发射,并且呈粉末状,最大发射波长在 424-436 Nm 范围内.两种配合物在粉末中都表现出接近统一的光致发光量子产率 (Plqy) 和非常好的升华特性.特别是,Ce-1Me-Otf在二氯甲烷和粉末中都发出深蓝色光,国际照明委员会
