The triplet state of gold(III) corroles is exploited for optical oxygen sensing. We report intense phosphorescence for gold(III) corroles in the near-IR, an optical window that is ideal for tissue transparency. Moreover, the triplet excited-state emission exhibits significant changes in intensity and lifetime over the 0-160 Torr O pressure range. This renders these compounds sensitive at biologically relevant pressures and overcomes the spectral limitations of palladium and platinum porphyrins for oxygen sensing in biology.
金（III）卟吩的三重态被用于光学氧传感。我们报道了金（III）卟吩在近红外区域有强烈的磷光，近红外是组织透明度的理想光学窗口。此外，三重激发态发射在0至160托的氧气压力范围内强度和寿命有显著变化。这使得这些化合物在生物学相关压力下具有敏感性，并克服了钯和铂卟啉在生物氧传感方面的光谱限制。
