Intervalence Charge Transfer

A transition of mixed-valence systems from Class II to Class III crossing the Class II–III borderline is achieved by four thienylene-bridged Mo2 dimers, and is probed using spectral parameters of intervalence charge transfer absorption (band energy, intensity and shape). This study offers fresh and detailed observations of optical behaviors of MV compounds in different regimes.

Configuration Coordinate

Configuration coordinate diagrams, which are normally used in a qualitative manner for the energy levels of active centers in phosphors, are quantitatively obtained here for intervalence charge transfer (IVCT) states of mixed valence pairs and metal-to-metal charge transfer (MMCT) states of heteronuclear pairs, in solid hosts.

Intervalence Charge Transfer

One-electron oxidation of the compound shown shows no evidence for intervalence charge transfer in the macrocylic ligand radical product. In contrast, related [{Pt(L)}3(μ3-ctc˙)]+ (H6ctc = cyclotricatechylene), exhibits class II mixed valency.
