series of bipolar-transporting europium(III) complexes containing carbazole and oxadiazole units were synthesized and characterized. Two intense UV absorption bands at around 286 nm and 352 nm, and sharply red emissions peaked at 614 nm were observed for these europium complexes in dichloromethane. Importantly, the bipolar-transporting europium(III) complexes exhibited higher thermal stability, more intense
合成并表征了一系列含有咔唑和恶二唑单元的双极传输euro(III)配合物。对于这些euro络合物在二氯甲烷中,观察到两个强烈的紫外吸收带,分别在286 nm和352 nm处,并且在614 nm处出现红色峰值。重要的是,与报道的三(二苯甲酰甲烷)(1,10-菲咯啉)euro(III)的红色生色团相比,双极传输-(III)配合物表现出更高的热稳定性,更强的紫外线在286 nm处的吸收以及两倍的光致发光量子产率。 )。
