| contents | Bright and long‐lasting aqueous peroxyoxalate chemiluminescence in cellulose microspheres Maidileyvis C. Cabello Erick L. Bastos Omar A. A. El Seoud Wilhelm J. Baader Photochemistry and Photobiology AbstractWater decreases the brightness of the peroxyoxalate chemiluminescence partially due to the hydrolysis of the oxalate reagent. Here, we show that encapsulation of an oxalate ester and the fluorescent activator in microspheres of cellulose esters increases the emission intensity 30 times compared to the same reaction in water without encapsulation, whereas the emission intensity decay rate constants are considerably lower. Emission intensities, rate constants and chemiluminescence quantum yields increase with increasing hydrogen peroxide concentrations. These results expand the potential of application of chemiluminescence, contributing for the development of ultrasensitive analytical methods. 10.1111/php.14040 http://onlinelibrary.wiley.com/termsAndConditions#vor |
