Inorganic Chromophores

Proposed excited-state decay pathway for [Co^IIW₁₂O₄₀]^6- illustrating the transient valence trap suggested by the long-lived excited state τ₂. W^V* indicates a fully delocalized heteropoly blue state. Stick diagrams of the core tetrahedron illustrate distortion of the heteroatom environment; polyhedral representations of the complete POM indicate the position of the photoexcited electron (blue shading).
