TL;DR: The photophysical properties of mononuclear Pt II chromophores of the general structural formulae: Pt(LL)(C CR) 2 and [Pt(LLL) + (LL ǫ = substituted or unsubstituated 2,2′-bipyridine; LLL Ã = substantially substituted 6′, 2.6′,2″-terpyridine, R Ã > alkyl) are described in this article.

TL;DR: Room temperature phosphorescence has been observed in a synthetically facile Pt(II) complex in fluid solution and static and time-resolved absorption and luminescence data are consistent with phosphorescence emerging from the appended CtriplebondC-pyrenyl units following excitation into the low energy dpi Pt --> pi* dbbpy metal-to-ligand charge transfer absorption bands.

TL;DR: Measurements confirm that electronic absorptions associated with the tBu3tpy radical anion simply do not account for the intense optical transitions observed in the excited state of the Pt(II) chromophores.

TL;DR: The photophysical properties of a new multichromophoric platinum(II) complex, Pt(dbbpy), C≡C−nap, were reported in four different solvent systems of varying polarity: toluene, 2methyltetrahydrofuran, dichloromethane, and acetonitrile as mentioned in this paper.

TL;DR: The kinetic data suggest that the presence of the MLCT states in Pt(dbbpy)(C[triple bond]C-pyrene)2 markedly accelerates the formation of the triplet state of the pendant pyrenylacetylide ligand, suggesting ultrafast wire-like energy migration in this molecule.
