In our pursuit of developing new light-harvesting molecules, we have synthesized six redox-active complexes of the formula [µ-1,X-BDT(Pt(tbtrpy))₂]²⁺ 2Y^- (X=3 or 4; Y=Cl¯, BF₄¯, or TCNQ¯; BDT = benzenedithiolate; tbtrpy = 4,4',4''-^tBu₃-2,2';6',2''-terpyridine). These molecules are characterized via solid-state and solution UV/VIS/NIR, ¹H-NMR and IR spectroscopy, and cyclic voltammetry. Changing the identity of the bridging thiolate ligand or the anion results in systematic shifts in the energies and extinction coefficients of the absorption bands of these molecules. The electrochemical behavior is such that all complexes exhibit reversible reductions characteristic of the π* terpyridine vacant orbitals and oxidations attributed to the platinum-thiolate filled orbitals.
