N,N'-dibromo-5,5-dimethylhydantoin and N-bromosuccinimide, chemical sources of singlet molecular oxygen: Observation of singlet oxygen with ultra-sensitive near-infrared chemiluminescence spectroscopy.

Abstract

N,N′-Dibromo-5,5-dimethylhydantoin and N-bromosuccinimide were found to be versatile and commercially available synthetic reagents for generating singlet molecular oxygen in organic solvents under mild conditions. Detection was by an ultra-sensitive near-IR chemiluminescence spectrometer designed and constructed in our laboratory.
