Oxygen-sensing elements containing single-layered structures of luminescent indicators of ruthenium(II) bipyridyl complexes on glass surfaces prepared by covalent attachment and LB deposition are described. They are capable of detecting gaseous oxygen concentration by luminescence quenching of the indicator with reproducible and large quenching efficiencies that are comparable to the best quenching efficiencies obtained by other ruthenium(II) polypyridine based complexes immobilized in matrixes. The large quenching efficiencies for both films imply that the probe complexes are effectively quenched by oxygen, which is probably due to the thin single-layered structures with large surface-to-area ratio and short distance between the probe complexes and oxygen.
描述了通过共价连接和LB沉积制备的在玻璃表面含有钌（II）联吡啶配合物发光指示剂单层结构的氧传感元件。它们能够通过指示剂的发光猝灭来检测气态氧浓度，具有可重现的高猝灭效率，可与固定在基质中的其他基于钌（II）多吡啶的配合物所获得的最佳猝灭效率相媲美。两种薄膜的高猝灭效率表明探针配合物被氧有效猝灭，这可能是由于具有大表面积与面积比以及探针配合物与氧之间距离短的薄单层结构所致。
