主 题:homochiral lanthanide cluster amino acid photoluminescence
摘 要:Four isostructural lanthanide compounds formulated as {[Ln4(μ3-OH)4(L-asp)3- (H2O)10](ClO4)5·10H2O}n (Ln=Nd (1), Sm (2), Eu (3), Gd (4); asp=aspartic acid) were synthe- sized by a conventional solution reaction. Their structures were characterized by single-crystal X-ray diffraction, IR spectroscopy and elemental analyses (EA). It reveals that they crystallize in the chiral P212121 space group. Their structures feature a homochiral three-dimensional (3D) lan- thanide-organic framework, which contains a cubic [Ln4(μ3-OH)4]8+ cluster sub-building unit (SBU). Additionally, the photoluminescence property of Eu compound was investigated in the solid-state at room temperature.
