The LangmuirâBlodgett films were prepared by hybridizing the clay minerals (synthetic saponite, synthetic hectorite and sodium montmorillonite) with the floating film of a cationic Ir(III) complex, [Ir(ppy)2(dc18bpy)]+ (ppy = 2-phenylpyridine; dc18bpy = 4,4â²-dioctadecyl-2,2â²-bipyridine). When the single-layered hybrid LB film was irradiated at 430 nm, it emitted light in the visible region, whose intensity responded reversibly to the pressure change of oxygen.
Langmuir-Blodgett薄膜是通过将粘土矿物(合成皂石、合成水云母和钠蒙脱石)与阳离子Ir(III)络合物[Ir(ppy)2(dc18bpy)]+(ppy = 2-苯基吡啶;dc18bpy = 4,4²-二十八烷基-2,2²-联吡啶)的悬浮液混合制备而成的。当单层混合LB薄膜在430纳米处受到照射时,会在可见光区域发光,其强度可逆地响应氧气压力的变化。
