For the first time, metal-polymer complexes have been synthesized using hyperbranched polyester polyfumaratomaleate as a matrix, the structure of which has been established by H NMR, IR, electron spectroscopy, and elemental analysis methods. The formation of complexes with Gd(III) and Dy(III) ions involving fumarate and maleate groups of the polyester was proved by IR and electron spectroscopy methods. It was established that the structure of the coordination units has the form of a square antiprism. The compositions and conditional logarithms of the stability constants of the complexes were determined. It was established that complexation with lanthanide ions promotes emission enhancement in the ligand.
首次以超支化聚酯聚富马酸马来酸酯为基质合成了金属-聚合物配合物,其结构已通过核磁共振氢谱、红外光谱、电子能谱和元素分析方法确定。通过红外光谱和电子能谱方法证明了聚酯的富马酸酯和马来酸酯基团与钆(III)和镝(III)离子形成了配合物。已确定配位单元的结构为方形反棱柱形式。测定了配合物的组成和稳定常数的条件对数。已确定与镧系离子的络合作用促进了配体发射增强。
