摘要

合成了一种新型钌(II)聚吡啶配合物,其中含有硅烷悬垂基团。该荧光材料与有机改性二氧化硅玻璃前驱体共价结合,得到适合光学氧传感的薄膜。这些膜具有良好的氧敏特性,与物理包裹的染料化学附着在支撑膜上相比,具有明显的优势。这种制备发光微孔玻璃薄膜的方法提供了适用于要求零染料浸出的应用的敏感膜。

The preparation of a sol–gel glass oxygen sensor incorporating a covalently bound fluorescent dye
The synthesis of a novel ruthenium(II) polypyridyl complex incorporating silane pendant moieties is described. This fluorescent material was covalently bound to an organically modified silica glass precursor to give thin films suitable for optical oxygen sensing. These films showed good oxygen sensitivity characteristics, and possess the distinct advantage over physically entrapped dyes of being chemically attached to the support membrane. This approach to the preparation of luminescent micro-porous glass films provides sensitive membranes suitable for applications where zero dye leaching is a requirement.
