Photophysics in bipyridyl and terpyridyl platinum(II) acetylides

The photophysical properties of mononuclear PtII chromophores of the general structural formulae: Pt(LL)(CCR)2 and [Pt(LLL)(CCR)]+ (LL = substituted or unsubstituted 2,2′-bipyridine; LLL = substituted or unsubstituted 2,2′:6′,2″-terpyridine; R = aryl or alkyl) are described. Topics related to their preparation, spectroscopy, photochemistry, and photophysics are reviewed.
