What is A novel sensitized chemiluminescence: Infrared emissions from thiazine dyes sensitized by singlet oxygen about?
## AJ-I unusual infrared chcmiluminescencc emission (8130 A) of mcthylenc b!?le, and other rhiazine dyes, sensitized by singlet molecular oxygen is reported. This chemiluminescence does not correspond to '&e ordinzy fluorescence of the dye and annot be explained by previously proposed mechanisms for singlet oxygen sensitized emissions of dyes. From energetic considerations singlet molecular oxygen in its 1 Zl state is postulated as the sensitizing agent for the thiazinc dye chemiluminescences. Schemes in which ' $ oxygen transfers electronic excitation energy (a), to the lowest triplet state of the dye, (b) to a combined mtitiplicity state of the lowest triplet state of the dye, and triplet ; molecular oxygen, or (c) to a charge-transfer state between the dye and oxygen, are compared. The chemilumines-! cence of methylene blue in aqueous solution may be used as a luminescent probe for ' .El oxygen.
