An inline sensing system for degradation of polyester resins is reported by Wolfgang Binder and co‐workers in article number 2100068, which is able to detect thermal degradation within poly(ester imide) resins, widely used as a coating material for copper wires in electric motors. Trifluoroacetyl‐functionalized stilbenes act as sensor molecules, detecting the release of alcoholic degradation products by solid‐state fluorescence spectroscopy, due to emission shifts induced by the hemiacetal formation, thus allowing monitoring of long‐term degradation of the PEI resins.
