Singlet Oxygen Generation from Polyaminoglycerol by Spin-Flip-Based Electron Transfer.

Reactive oxygen species have drawn attention owing to their strong oxidation ability. In particular, the singlet oxygen (O) produced by energy transfer is the predominant species for controlling oxidation reactions efficiently. However, conventional O generators, which rely on enhanced energy transfer, frequently suffer from poor solubility, low stability, and low biocompatibility.
