Abstract:

Chemiluminescence (CL) reactions were studied in a model system based on a phase diagram which was composed of Triton X-100, 2-butanol, toluene, and H2O. The CL reaction was achieved by using trichlorophenyl oxalate, H2O2, and perylene as the fluorophore. The intensity of light (I0) and t1/2 depend on both reactant concns. and phase compn. The CL reaction was conducted in W/O microemulsions, and an inverse relation between I0 and t1/2 was found. These two parameters could also indicate the transition from a W/O (water-in-oil) emulsion to a W/O microemulsion. The effect of medium polarity was evaluated by fluorescence, absorbance, and chemiluminescence spectra. [on SciFinder(R)]
