镱(Ⅲ)卟啉配合物的合成、结构表征和近红外光谱研究
Synthesis, Characterization and Near-infrared Photoluminescence of Ytterbium(Ⅲ) Monoporphyrinate Complexes
摘要
Abstract
A series of ytterbium (Ⅲ) monoporphyrinate complexes (2a-2e) , bearing different substituents on meso- or B- position, were synthesized and characterized via UV-Vis, ~1H NMR, high-resolution mass spectra and elemental analysis. The photoluminescent properties of the complexes, especially in the near-infrared region, were studied in detail. Related quantum yield and fluorescence lifetime show that the energy is transferred to the excited state of ytterbium(Ⅲ) ion caused by excitation of the π→π~* transitions of porphyrinate, which led to strong NIR emission. The light-emitting efficiency of the complexes with electron-donating substituents on meso-position is better than that of complexes with electron-withdrawing substituents, while the complex with bromide on B-position possesses the poor ability of light-emitting.关键词
