Lanthanides doped coordination polymers (CPs) with different binding motifs were synthesized to investigate the influence of the different fluorine positions in the structure on the decay time τ of the excited states. Fluorine can be integrated into the network mechanochemically via a fluorinated organic linker, here barium tetrafluoroterephthalate Ba(p-BDC-F₄)₂ or directly via a metal-fluorine bond (barium terephthalate fluoride BaF(p-BDC)_0.5). The CP with a metal-fluorine bond shows the highest lifetime of the excited states of lanthanides (Eu³⁺, Tb³⁺ or Eu³⁺& Tb³⁺). The excitation of the lanthanides can be performed directly via the excitation wavelength typical for lanthanides and via the excitation wavelength of the linker. This enabled the simultaneous excitation of Eu³⁺ and Tb³⁺ in one CP. In the emission spectra (λ_em = 393 nm) of the mixed doped CPs (Eu³⁺ and Tb³⁺) the bands of both lanthanides can be observed. The integration into the crystal lattice and the homogeneous distribution of the lanthanides in the CPs is shown by X-ray diffraction, TEM, STEM-EDS measurements and the long decay times.

合成了具有不同结合基序的掺杂镧系元素的配位聚合物（CPs），以研究结构中不同氟位置对激发态衰减时间τ的影响。氟可通过氟化有机连接基机械地整合到网络中，此处为四氟对苯二甲酸钡Ba（p -BDC-F ₄）₂或直接通过金属-氟键（对苯二甲酸钡氟化BaF（p -BDC）_0.5）。具有金属-氟键的CP表现出镧系元素（Eu ³⁺，Tb ³⁺或Eu ³⁺和Tb ³⁺）。镧系元素的激发可以直接通过镧系元素典型的激发波长和接头的激发波长来进行。这使得能够在一个CP中同时激发Eu ³⁺和Tb ³⁺。在 混合掺杂CP（Eu ³⁺和Tb ³⁺）的发射光谱（_λem = 393 nm）中，可以观察到两种镧系元素的谱带。通过X射线衍射，TEM，STEM-EDS测量和较长的衰变时间显示出CP中镧系元素在晶格中的整合和镧系元素的均匀分布。
