The oxygen sensing mechanism of a triphenylamine-based cyclometalated platinum(II) complex
Oxygen sensing Luminescence mechanism Quenching
2023/3/1
Triphenylamine-based cyclometalated platinum(II) (TCP) emits phosphorescence at room temperature. The phosphorescence was quenched by oxygen molecule, which means that TCP is a good candidate for oxyg...
