Studies of the Chemiluminescence of Several Xanthene Dyes. V. Blue Emission from an Excited State of a Reaction Product

Studies of the Chemiluminescence of Several Xanthene Dyes. V. Blue Emission from an Excited State... We have found that the chemiluminescence emission of several xanthene dyes with hydrogen peroxide is comprised of two emission components; one is a greenish-yellow emission whose spectral distribution is similar to that of the fluorescence of the dye, and the other is a blue emission similar to the fluorescence band which appears during the course of the reaction. Summarizing the results, we can conclude that the chemical formation of an excited species from the oxidation of a dye, and an energy-transfer process from the species to an unoxidized dye, are likely to be the mechanism for the luminescent reaction. Certain dyes, uranin, eosin Y, eosin R, erythrosin B, 2′,7′-dichlorofluorescein, mercurochrome, rhodamine B, rhodamine 6G, and rhodamine S, showed similar characteristic chemiluminescence emissions, whereas phloxine, rose bengale, 4-nitrofluorescein, 4,5,6,7-tetrachlorofluorescein, sulfonfluorescein, and pyronine G did not chemiluminesce under comparable conditions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of the Chemical Society of Japan Oxford University Press

Abstract

We have found that the chemiluminescence emission of several xanthene dyes with hydrogen peroxide is comprised of two emission components; one is a greenish-yellow emission whose spectral distribution is similar to that of the fluorescence of the dye, and the other is a blue emission similar to the fluorescence band which appears during the course of the reaction. Summarizing the results, we can conclude that the chemical formation of an excited species from the oxidation of a dye, and an energy-transfer process from the species to an unoxidized dye, are likely to be the mechanism for the luminescent reaction. Certain dyes, uranin, eosin Y, eosin R, erythrosin B, 2′,7′-dichlorofluorescein, mercurochrome, rhodamine B, rhodamine 6G, and rhodamine S, showed similar characteristic chemiluminescence emissions, whereas phloxine, rose bengale, 4-nitrofluorescein, 4,5,6,7-tetrachlorofluorescein, sulfonfluorescein, and pyronine G did not chemiluminesce under comparable conditions.
