合成了一种新的含N和S的高分子铑配合物,通过运用红外光谱和XPS电子能谱测试手段,分析表征了配合物存在的NRh配位键和SPh配位键,发现高分子配合物中除了形成配位键的N和S外,还含有未参与配位的N和S;同时发现,这些未配位的N和S在该高分子铑配合物中能发生分子内取代反应,这一独特性质有助于提高该化合物的热稳定性.

A new copolymer rhodium complex, containing un-coordinated Nitrogen and Sulfur donor atoms, is reported here. On the basis of the evidence of its IR and XPS spectrum analysis, the coordinate bonds of N→Rh and S→Rh have been defined in this new complex. Following the tracks of its IR and XPS spectrum change, we found that the complex exists un-coordinated donor atoms (name as free donor atoms in the remainder of discuss), and these free donor atoms can induce an intramolecular substitution reaction in this new copolymer complex. Its distinctive property helps to improve its heated stability.
