“…This relaxation results in the appearance of new optical transitions in the absorption spectrum at energies beneath the maintransition upon charge injection. These transitions have been detected experimentally [6][7][8][9][10][11][12][13][14] and are in good agreement 15 with the quantum chemical calculations of Cornil et al [16][17][18][19] performed on isolated oligomers ͑see Fig. 2͒ and earlier tightbinding models of isolated, one-dimensional polymer chains developed by Su, Schrieffer, and Heeger ͑the SSH model͒ ͑Ref.…”

“…To our knowledge, such a pronounced vibrational structure in the bleaching signal has not been previously reported for a conjugated polymer using CMS or chemical doping of thin solid films. 10,11 The following experimental observations suggest that the charged species in high-mobility P3HT FET's is a singlycharged polaronic carrier, as opposed to a doubly charged bipolaronic species:…”

“…0.02 spins per meric unit, corresponding to 1 spin per 50 monomer units on average. This is a relatively high value compared with other undoped conjugated polymers like polythiophene (PT) or polypyrrole where the residual number of spins associated with polymer defects can be as low as 1 × 10 −4 [32] or 5 × 10 −3 [33] spins per mer accordingly. With increasing potential, concentration of spins changes little at first, however onward from −0.9 V a gradual increase is observed.…”

“…The polaron band red-shifts considerably with the doping level of the polymer, [23] and with the intermolecular interaction of the oligomers, [24] but its peak absorption cross-section s p Figure 2. FTIR spectra of a rr-P3HT film acquired sequentially after different in-situ exposure to cleanroom air.…”
