| 内容記述 | Light-induced electron spin resonance (LESR) measurements have been performed on a quasi-onedimensional(Q1D) iodo-bridged diplatinum complex Pt_2(n-pentylCS_2)_4I, where the thermal activation of solitons has been reported in the doubly-degenerate alternate-charge-polarization (ACP) (Pt^2+-Pt^3+-I−-Pt^3+-Pt^2+) state formed below 210 K. An enhancement of ESR signal has been detected due to the photogeneration of Pt^3+ spins below about 30 K, as confirmed through the observed g values of g∥=1.980 and g⊥=2.215 with the external field parallel and perpendicular to the chain axis, respectively. The LESR linewidth is clearly smaller than that of the ESR signal of Curie spins observed under the dark condition, whereas it exhibits uniaxial anisotropy similar to that of the dark ESR due to the anisotropic hyperfine interaction of Pt and iodine nuclear spins. The small LESR linewidth compares well with the motionally-narrowed ESR linewidth of thermally activated solitons at elevated temperatures, indicating that the photogenerated spins are mobile. Furthermore, bimolecular recombination of photogenerated spins has been demonstrated from the excitation power dependence and decay curves of LESR intensity. These LESR features strongly suggest that the mobile spins are photogenerated solitons, which agrees with theoretical predictions. | |||||
