The phosphorescence quantum yield Phi(r) at the point r inside the medium is dependent on the local concentration of the quencher (oxygen) and is proportional to the phosphorescence lifetime τ(r). The quantum yield in the absence of the quencher Phi_{0} is the same for all probe molecules throughout the volume, provided that the probe molecules do not interact with the environment. Dendritically protected phosphorescent probes are designed to exclude such interactions. They have been shown to retain their photophysical properties in physiological environments, e.g., in the blood serum and interstitial fluid.
