The 2D isostructural lanthanide-organic frameworks [Ln(4-SBA)(IP)OH] · 1.5H2O (Ln = Sm 1, Eu, 2 Gd3 and Tb 4 ; 4-SBA = 4-sulfobenzoate and IP = 1H-imidazo[4,5-f][1,10]-phenanthroline) display different luminescent behavior. White light emission was realized by introducing single dopant Eu(III) and codopants Eu(III)/Gd(III) or Eu(III)/Tb(III) into the Sm(III) framework for the first time.
二维同构镧系有机框架化合物[Ln(4-SBA)(IP)OH]·1.5H₂O（Ln = Sm 1、Eu 2、Gd 3和Tb 4；4-SBA = 4-磺酸苯甲酸酯，IP = 1H-咪唑并[4,5-f][1,10]-菲咯啉）表现出不同的发光行为。首次通过将单一掺杂剂Eu(III)以及共掺杂剂Eu(III)/Gd(III)或Eu(III)/Tb(III)引入Sm(III)框架实现了白光发射。
