以3,4-二苯基噌啉为环金属配体,二氢二(l-甲基-2-巯基咪唑)硼为解离配体合成一种中性环金属铱配合物Ir(dpci)2{H2B(mt)2}。配合物的结构通过质谱、核磁进行表征。结果表明:Ir(dpci)2{H2B(mt)2}在二氯甲烷溶液中的最大发射波长为622 nm,在固态时的最大发射波长为720 nm;溶液中的磷光寿命为0.5μs,量子产率为0.54。与金属离子的荧光滴定实验表明该配合物具有对Fe3+的选择性磷光淬灭性能,能作为Fe3+的磷光探针。
Synthesis of a Neutral Iridium Complex Ir (dpci) with 3,4-Diphenylcinnamate as Ring Metal Ligand and Dihydrodibenz (l-methyl-2-mercaptoimidazole) 2 {H2B (mt) 2}. The structure of the complex was characterized by MS and NMR. The results show that the maximum emission wavelength of Ir (dpci) 2 {H2B (mt) 2} in dichloromethane solution is 622 nm and the maximum emission wavelength in solid state is 720 nm. The phosphorescence lifetime of the solution is 0.5 μs. The quantum The yield is 0.54. Fluorescence titration experiments with metal ions showed that the complex has selective phosphorescence quenching ability to Fe3 + and can be used as a Fe3 + phosphorescence probe.
