摘要：

[Ru(bipy)3]2+ chemiluminescence: The mechanisms governing the selectivity of the luminescence of the [Ru(bipy)3] 2+ complex (bipy=2,2′-bipyridyl) were investigated using continuous flow EPR spectroscopy. The radical intermediates of substrates thought to evoke or quench the emission from this reagent were characterized in the light-producing pathway. © 2011 WILEY-VCH Verlag GmbH & Co.
