  Facile preparation of neutral monoporphyrinate lanthanide complexes with strong near-infrared emission

  摘要：

  Ytterbium (III) acetylacetonate reacts with 5,10,15,20-tetraphenylporphyrin (H2TPP) and 5,10,15,20-tetra(4-bromophenyl)porphyrin (H2TBrPP) in 1,2,4-trichlorobenzene and forms unexpected acetate-bridged dimer and propionate-coordinated monomer of monoporphyrinate ytterbium (III) complexes, respectively, whereas interaction of ytterbium (III) acetate with H2TPP gives stable acetate-coordinated monomer with two labile methanol binding directly to metal center. This compound reacts readily with 1,10-phenanthroline derivatives to give eight-coordinate monoporphyrinate ytterbium (III) complexes with strong near infrared emission efficiency.

  The new erbium(III) and ytterbium(III) monoporphyrinate complexes were synthesized and hybridized into silica xerogel frameworks though the coordination of 5-(N,N-bis(3-propyl)ureyl-1,10-phenanthroline to the lanthanide ions. The complexes are eight-coordinate with strong emissions in solution in the near-infrared region. The resulting silica films are transparent, homogenous, and exhibit strong mechanical strength. The scanning electron microscope and atomic force microscope study reveals that the surface of the film is porous with the silica in particulate or rod shapes. Upon visible light excitation, the fluorescence of the porphyrin at ∼ 649 nm with lifetimes of ∼ 3.4 and 3.8 ns for erbium(III) and ytterbium-hybridized films were observed, respectively. The erbium- and ytterbium-hybridized films gave characteristic emissions at 1538 nm with a lifetime of 0.6 μs and at 980 nm with a lifetime of 6.6 μs, respectively. They exhibited a 50 to 70% decrease in lifetime compared to their parent complexes in toluene.

  通过 5-(N,N-双(3-丙基)脲基-1,10-菲罗啉)与镧离子的配位，合成了新的单卟啉酸铒(III)和镱(III)配合物，并将其杂化到二氧化硅 xerogel 框架中。这些配合物为八配位，在溶液中具有很强的近红外辐射。生成的二氧化硅薄膜透明、均匀，并具有很强的机械强度。扫描电子显微镜和原子力显微镜研究表明，薄膜表面多孔，二氧化硅呈颗粒状或棒状。在可见光激发下，卟啉在 649 nm 处发出荧光，铒（III）杂化薄膜和镱杂化薄膜的荧光寿命分别为 3.4 ns 和 3.8 ns。铒和镱杂化薄膜在 1538 纳米波长和 980 纳米波长上分别发出了寿命为 0.6 μs 和 6.6 μs 的特征辐射。与甲苯中的母体复合物相比，它们的寿命缩短了 50% 到 70%。

  Substitution reactions between [Yb(TPP)(OOCCH3)(CH3OH)2] (1) and neutral bidentate ligands NN led to the formation of monoporphyrinate ytterbium(III) complexes [Yb(TPP)(OOCCH3)(NN)] (TPP = 5,10,15,20-tetraphenylporphyrinate anion; NN = 4-methyl-1,10-phenanthroline (2), 1,10-phenanthroline (3), 4,7-dimethyl-1,10-phenanthroline (4), 5,6-epoxy-5,6-dihydroxy-1,10-phenanthroline (5) and 2,2′-dipyridylamine (6)). Single-crystal X-ray diffraction analysis revealed that ytterbium(III) ions in 1 and 6 were seven-coordinate with OOCCH3− in monodentate coordination, whereas those in 2, 3, 4 and 5 were eight-coordinate with OOCCH3− in bidentate coordination. The visible emission (650 and 720 nm) from the porphyrin and near-infrared (NIR) emission (980 and 1003 nm) from ytterbium(III) ion were observed for all complexes. The eight-coordinate complexes exhibited stronger NIR emission and longer lifetimes in toluene solution than the seven-coordinate complexes. The NIR emission of complexes with decreased lifetimes was also observed when they were blended into organic polymer PMMA.

  [Yb(TPP)(OOCCH3)(CH3OH)2](1)与中性双齿配体 NN 之间的取代反应导致形成单卟啉酸镱(III)配合物 [Yb(TPP)(OOCCH3)(NN)]（TPP = 5,10,15,20-四苯基卟啉酸阴离子；NN = 4-甲基-1,10-菲罗啉 (2)、1,10-菲罗啉 (3)、4,7-二甲基-1,10-菲罗啉 (4)、5,6-环氧-5,6-二羟基-1,10-菲罗啉 (5) 和 2,2′-二吡啶基胺 (6)）。单晶 X 射线衍射分析表明，1 和 6 中的镱(III)离子与 OOCCH3- 呈单配位，为七配位；而 2、3、4 和 5 中的镱(III)离子与 OOCCH3- 呈双配位，为八配位。所有配合物都能观察到卟啉的可见光发射（650 纳米和 720 纳米）和镱（III）离子的近红外发射（980 纳米和 1003 纳米）。与七配位配合物相比，八配位配合物在甲苯溶液中的近红外发射更强，寿命更长。将这些配合物与有机聚合物 PMMA 混合后，还观察到配合物的近红外发射和寿命缩短。
