Solitons, polarons and their dynamics in mixed-valence halogen-bridged MX-chains.

چکیده
This article describes the photo-generation processes of elementary excitations such as solitons and polarons, and their dynamics in the one-dimensional (1D) halogen-bridged Pt compound [Pt(en)2Br](ClO4)2. Spin-solitons were photo-generated via relaxation processes of CT excitons and self-trapped excitons, made evident by photo-induced absorption and photo-induced electron spin resonance spectra. Polarons were not generated from CT excitons. Diffusion of spin-solitons on the 1D chain was studied quantitatively by analysing 1H NMR spin-lattice relaxation times (T1).

A template-directed synthetic approach to halogen-bridged mixed-valence platinum complexes on artificial peptides in solution.
A template-directed synthetic approach to halogen-bridged mixed-valence platinum complexes has been performed in organic media using, for instance, a synthetic peptide bearing two bis(ethylenediamine)-based Pt(IV) complexes with two axial bromide anionic ligands, [(Pt(IV)Br2(en))2](RSO3)4, and a [Pt(II)(en)2](RSO3)2 complex (R = (C12H25OCH2)2CHO(CH2)3-).
متن کاملHalogen Photoelimination from Dirhodium Phosphazane Complexes via Chloride-Bridged Intermediates.
Halogen photoelimination is a critical step in HX-splitting photocatalysis. Herein, we report the photoreduction of a pair of valence-isomeric dirhodium phosphazane complexes, and suggest that a common intermediate is accessed in the photochemistry of both mixed-valent and valence-symmetric complexes. The results of these investigations suggest that halogen photoelimination proceeds by two sequ...
متن کاملTuning of the CDW in the Halogen-Bridged Transition-Metal Linear-Chain Compounds
Local-density-approximation calculations are used to show that the metal-metal distance along the chains controls the charge-density wave (CDW) in halogen-bridged transition-metal linear-chain (MX) compounds. The strength of the CDW can be understood in terms of a two band Su-Schrieffer-Heeger model if a hard-core ion-ion repulsion potential is also added. We predict a second-order phase transi...
متن کاملVIII-H-1 Most Stable Metallic Phase of the Mixed-Valence MMX-Chain, Pt2(dtp)4I (dtp: C2H5CS2) in Purely d-Electronic Conductors Based on the Transition-Metal Complex OTSUBO,
A powerful method to determine the hidden structural parameters in functional molecules has been developed. Local valence arrangements that dominate the material properties are sometimes not three-dimensionally ordered. This method that comprises diffuse Xray scattering and resonant X-ray scattering is suitable in such cases. Using this method, we present clear evidence of the low-dimensional v...
متن کاملEffect of quantum lattice fluctuations on the optical-absorption spectra of halogen-bridged mixed-valence transition-metal complexes
The effect of quantum lattice fluctuations on the optical-absorption spectra in the ground state of halogen-bridged mixed-valence transition-metal linear-chain complexes is studied by using a one-dimensional extended Peierls-Hubbard model. The nonadiabatic effects due to finite phonon frequency ωπ > 0 are treated through an energy-dependent electron-phonon scattering function δ(k, k) introduced...
