Thermochromic absorption and photoluminescence in [Pt(ppy)(mu-Ph2pz)]2.
The temperature effects on the spectral properties and photophysics of a new d(8)-d(8) dinuclear Pt(II) chromophore, [Pt(ppy)(mu-Ph(2)pz)](2) (ppy is 2-phenylpyridine and Ph(2)pz is 3,5-diphenylpyrazolate), have been investigated. The thermochromic shifts are tentatively ascribed to intramolecular sigma interactions between the two pseudocofacial d(z(2)) orbitals. Substantial emission profile changes occur in the solid state, solution, and doped polymer films.
