A reversible photophysical degradation of P1VN/PMMA blends is observed at 77 K upon prolonged irradiation. In the dilute blends, the ratio of singlet excimer to monomer emission increases as exposure time increases. However, thermal annealing even below the glass transition temperature can restore the original ratio of singlet excimer to monomer.
