摘要：
A samarium hybrid with porphyrin and amino acid as mixed ligands {[Sm(His)(H2O)] [Sm(H3O)(3)](H2TPPS)(2)}center dot 5H(2)O (1) (His = histidine; H6TPPS = tetra(4-sulfonatophenyl) porphyrin) has been synthesized via a hydrothermal reaction and characterized by single-crystal X-ray diffraction. Compound 1 is crystallized in the space group Pi of the triclinic system. Compound 1 is characteristic of a three-dimensional (3-D) open framework with the samarium ions in two types of coordinating environments and a saddle-distorted nonplanar porphyrin macrocycle. Compound 1 exhibits fluorescence in the red region. The fluorescence lifetime of 1 is 15.65 ns and the emission quantum yield is 4.1%. The CV/DPV, UV-vis and FT-IR are also reported in detail.
