Abstract

A new Eu(III) compound, namely [Eu(L)(H₂O)]n (1 H₃L = biphenyl-3,4’,5-tricarboxylic acid), has been hydrothermally synthesized and structurally characterized. Single-crystal X-ray diffraction analysis indicated that Compound 1 crystallizes in the tetragonal chiral space group I4₁ and displays a twofold interpenetrated 3D framework containing 1D right-handed 4₁ helical chains as building subunits. Moreover, Compound 1 has intense Eu(III) characteristic emission with the quantum yield of 68.2%.

摘要

已经水热合成了一种新的Eu（III）化合物，即[Eu（L）（H ₂ O）] n（1 H ₃ L =联苯-3,4'，5-三羧酸）。单晶X射线衍射分析结果表明，化合物1个结晶的手性四方空间群在我4 ₁和显示双重互穿含1D右旋4支3D框架₁螺旋链作为建设亚基。此外，化合物1具有强烈的Eu（III）特征发射，量子产率为68.2％。
