 | Vardeny, Zeev Valentine; Ehrenfreund, Eitan A. | Illumination-induced metastable polaron-supporting state in poly(p-phenylene vinylene) films | We found an illumination-induced metastable polaron-supporting state in films of a soluble derivative of poly-p-phenylene vinylene (MEH-PPV). Pristine, nonilluminated MEH-PPV polymer films do not show longlived photogenerated polarons. Prolonged UV illumination, however, is found to induce a revers... | Metastable polaron-supporting state; Poly(p-phenylene vinylene); PPV; MEH-PPV; Excitons | 2007-07 |
