ABSTRACT

Investigation of effective photodynamic therapy (PDT) reagents needs to observe ¹O₂. The observation of the amount of photogenerated ¹O₂ emission at 1,270 nm is one of the engaged method for ¹O₂ generation evolution quantitatively, however it is convenient to observe fluorescent spectra relevant to a phosphorescence of singlet molecular oxygen due to the energy transfer from PDT reagents to ³O₂. Ir(III) complex containing a thioglucose tetraacetate-conjugated bipyridyl ligand were synthesized newly, and the photogeneration of ¹O₂ was confirmed by measurement of a phosphorescence of singlet molecular oxygen.

KEYWORDS

Photosensitizer, photodynamic therapy (PDT) reagents, singlet oxygen, glucose, iridium(III) complex, warburg effect.
