合成了亲脂性双核铼配合物fac-[{Re(CO)3(d19-phen)}2(4,4′-bipyridylacetylene)](OTf)2,将此配合物均匀地分散到聚苯乙烯(PS)和聚甲基丙烯酸甲酯(PMMA)中,通过电纺方法,得到复合材料纤维,并系统地研究了它们的氧传感性能。分别用线性Stern-Volmer模型,Demas双格位模型以及Lehrer模型对所得到的Stern-Volmer曲线进行了拟合,实验结果表明,这种复合纤维氧传感材料显示了短的响应时间,可逆的氧传感信号,而且由于含有亲脂性的长链烷烃配体的存在,使得铼配合物在聚合物中分散均匀,从而得到线性关系较好的Stern-Volmer曲线。
The complex of fac - [{Re (CO) 3 (d19-phen)} 2 (OTf) 2 with lipophilic binuclear rhenium complex was synthesized and dispersed in polystyrene PS) and polymethylmethacrylate (PMMA), the composite fibers were obtained by electrospinning method, and their oxygen sensing properties were systematically investigated. The Stern-Volmer curves were fitted by the linear Stern-Volmer model, the Demas double-lattice model and the Lehrer model respectively. The experimental results show that the composite fiber oxygen sensing material shows a short response time, reversible Oxygen sensor signal, and due to the presence of lipophilic long-chain paraffinic ligands, the rhenium complexes are uniformly dispersed in the polymer to obtain the Stern-Volmer curve with good linearity.
