 | Vardeny, Zeev Valentine | Studies of charged excitations in ∏-conjugated oligomers and polymers by optical modulation | We have studied photogenerated charged excitations in sexithiophene and a variety of p-conjugated polymers by photoinduced absorption (PA) and PA-detected magnetic resonance. We found distinct spin signatures for polarons and bipolarons, which enabled us to separate their contributions to the PA spe... | Pi-conjugated oligomers; Pi-conjugated polymers; Charged excitations; Optical modulation; Spin signatures; Bipolarons; Photoexcitation | 1996-08 |
