摘要: A new lanthanide porphyrin, [Sm(H3TPPS)]n·nH2O (1, H6TPPS=tetra(4-sulfonatophenyl)porphyrin), has been synthesized through a hydrothermal reaction and structurally characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the P4/mcc space group of tetragonal system: a=15.3683(12), c=9.895(2)Å, V=2337.0(5)Å3, C44H29N4O13S4Sm, Mr=1100.30, Z=2, Dc=1.564 g/cm3, S=1.063, μ(Mo)=1.502 mm-1, F(000)=1102, R=0.0583 and wR=0.1666. Compound 1 is characteristic of a three-dimensional (3-D) framework with a slightly distorted square-antiprism eight-coordinated Sm3+ ion. Fluorescent study revealed that compound 1 exhibits an emission in the red region. The fluorescence quantum yield and lifetime of 1 were determined to be 3.5% and 9.1 ns, respectively. UV-vis absorption spectra were also investigated.
