Thermochromic Absorption and Photoluminescence in [Pt(ppy)(μ-Ph2pz)]2

The temperature effects on the spectral properties and photophysics of a new d8−d8 dinuclear PtII chromophore, [Pt(ppy)(μ-Ph2pz)]2 (ppy is 2-phenylpyridine and Ph2pz is 3,5-diphenylpyrazolate), have been investigated. The thermochromic shifts are tentatively ascribed to intramolecular σ interactions...

Summary:The temperature effects on the spectral properties and photophysics of a new d8−d8 dinuclear PtII chromophore, [Pt(ppy)(μ-Ph2pz)]2 (ppy is 2-phenylpyridine and Ph2pz is 3,5-diphenylpyrazolate), have been investigated. The thermochromic shifts are tentatively ascribed to intramolecular σ interactions between the two pseudocofacial d z 2 orbitals. Substantial emission profile changes occur in the solid state, solution, and doped polymer films.
