摘要
以2,2′-联吡啶为原料,合成了Ru(Ⅱ)联吡啶配合物,其结构经^(1)H NMR,^(13)C NMR和MALDI-TOF表征。测试并分析了化合物的紫外吸收、室温(298 K)光致发光和低温(77 K)光致发光性能。结果表明:配合物的紫外吸收性能优于Ru(bpy)3(PF 6)2;发射波长位于654,676,680,689 nm处,说明引入不同的取代基团,能够有效调控配合物的发射波长。
2,2′-bipyridine Ru(Ⅱ)metal complexes were synthesized from 2,2′-bipyridine.Their UV absorption,room temperature(298 K),and low temperature(77 K)photoluminescence spectra were measured and analyzed.The structures of the compounds were identified by ^(1)H NMR,^(13)C NMR and MALDI-TOF.The UV absorption spectra showed that the absorption of the new complex was better than Ru(bpy)3(PF 6)2.The emission spectra showed that the emission wavelength of the new complex was at 654,676,680,689 nm,indicating that the introduction of different substituents can effectively regulate the emission wavelength of the complex.The complex can be used as a new candidate for electrochemiluminescence.
