获得了镱与β位含有取代基的不对称卟啉的新配合物，并通过元素分析、红外、紫外-可见吸收和发光光谱进行了表征。在 295K 的 DMF 溶液中研究了这些配合物的电子吸收、发光和发光激发光谱。在 Soret 波段 (400–430nm) 激发下观察到镱卟啉在近红外 (IR) 光谱区 (λmax=980nm) 的 4f 发光。还研究了卟啉大环中的取代基对4f-发光性质的影响。
New complexes of ytterbium with asymmetric porphyrins containing substituents in β-positions were obtained and characterized by elemental analysis, IR, UV–vis absorption and luminescence spectroscopy. Electronic absorption, luminescence and luminescence excitation spectra of these complexes were studied at 295K in DMF solutions. The 4f-luminescence of ytterbium–porphyrins in the near infrared (IR) spectral region (λmax=980nm) is observed under excitation in Soret band (400–430nm). The effect of substituent in porphyrin macroring on the 4f-luminescent properties was also investigated.
