三(2,2′-联吡啶)二氯化钌(II) 六水合物是一种金属络合物，被用作发光染料。处于基态的金属络合物能够被可见光激发，形成自旋允许激发态。该激发态经过无辐射去活化，非常快速地形成自旋禁阻长期发光激发态。它被广泛用于电发光设备中。 用途： 合成用于氧化酶生物传感器的复合催化剂。 用作生物分析中多重信号传导的发光体。 用于活细胞中的氧气评估。 RTDP was used to measure the oxygen concentration in a microfluidic chip. A new hybrid material for oxidase based biosensors was prepared by combining Wells-Dawson K7[H4PW18O62]·18H2O (PW18) and RTDP. Silica nanoparticles doped with RTDP render them fluorescent, radio opaque and paramagnetic.
