Gold Corroles as Near-IR Phosphors for Oxygen Sensing

Gold Corroles as Near-IR Phosphors for Oxygen Sensing
Penelope J. Brothers, David C. Powers, Christopher M. Lemon, Daniel G. Nocera
The photophysical properties of a series of β-brominated gold(III) corrole complexes are examined. These compounds exhibit intense phosphorescent emission in the near-IR (780−795 nm) with a ∼80 μs lifetime. This feature is significantly quenched under ambient oxygen, rendering these complexes oxygen sensors over the biologically relevant 0−160 Torr O2 pressure range.
