英文摘要： The effetive synthesis method and technology to prepare inexpensive, high-performance novel organic/inorganic hybrid optical oxygen sensing nano-fibers will be explored from the viewpoints of the dispersibility of Ru(II) diimine complex, the oxygen diffusion rate and the stability of the luminore probe whinth the matrix. Then, the intrinsic correlation of the microenvironment controlling and the oxygen sensing properties will be investigated in this project. Utilizing the unique physical and chemical properties of matrix materials in which its microenvironment is easily tailored, and the bi-functional characteristic of the organic modified silicate ester, directional orientation of Ru(II) complexes on the nano-fibers materials can be obtained via the electrostatic spinning technology, and the micro-environment homogeneous distribution of Ru(II) probe molecules within the framework of the matrix will be achieved. Through this strategy, the signal-shifting problem caused by the leaking of probe complex due to the weak physical interation between the matrix and the luminophore will be solved. Obvious improvement in photo-thermal stability, long-term stability and reproducibility of the novel Ru(II) covalently grafted nano-fibers oxygen sensing materials will be expected. This research has important theoretical valu
