**Dramatic fluorescence bursts** (see Figure and cover) from conjugated polymers are observed upon exposure to air. The burst occurs prior to photo‐oxidation and is imaged in single molecules of a ladder‐type polymer, but is also found in bulk films. Triplet shelving is identified as an important me
## Abstract **Nonvertical triplet energy transfer** in solid conjugated polymer films is demonstrated for the first time using 1,3,5,7‐cyclooctatetraene, a compound that can efficiently quench the phosphorescence of polyfluorene without affecting its fluorescence (see spectra). The results suggest
