Disclosed is a compound characterized by comprising a linker, an oxygen-concentration-responsive phosphorophore which is linked to a first end of the linker, and a fluorophore which is lined to a second end of the linker. In the compound, it is preferred that the triplet level of the phosphorophore be lower than that of the fluorophore. The compound can be used as an oxygen-responsive luminescent probe.
