Monitoring on the radicals in early stage of polymer degradation is essential to unveil mechanism and achieve rational management polymers. However, it challenging provide a sensitive monitoring polymers, especially for nonemissive radicals. In this contribution, we proposed electrochemiluminescence (ECL) monitor radical behaviors aromatic It was disclosed that carbon-centered were generated photodegraded facilitating formation hydroxyl superoxide anion Accordingly, ECL intensities polymers continuously promoted with prolonged phototreatment from 0 12 h. comparison, obvious signals could only be detected after long-term by conventional electron spin resonance measurements. Additionally, thermal treatment showed no profound effect promotion due different reaction pathways. Therefore, have realized providing valuable information evolution.
