Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is a ....Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is applicable to polymerization kinetics studies, as well as providing new means for the determination of materials lifetimes. The development of pro-fluorescent markers as indicators for polymer degradation would be a significant outcome for materials where component failure has a major negative impact.Read moreRead less
