Abstract
<jats:title>Abstract</jats:title><jats:p>Metalloligands <jats:bold>L1</jats:bold> and <jats:bold>L2</jats:bold> consisting of directional bis(terpyridine)ruthenium(II) units and bipyridine moieties were constructed by amide formation. From these metalloligands two Ru–Pt heterobimetallic complexes <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> were derived by a building‐block method by means of platination with [PtCl<jats:sub>2</jats:sub>(dmso)<jats:sub>2</jats:sub>]. Both bimetallic complexes <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> feature metal‐to‐ligand charge transfer (MLCT) absorptions, and emission occurs at room temperature in fluid solution from <jats:sup>3</jats:sup>MLCT(Ru) states in all cases. Energy transfer from platinum to ruthenium is observed in <jats:bold>2</jats:bold> but not in <jats:bold>1</jats:bold> (light harvesting). The one‐electron‐reduced species [<jats:bold>1</jats:bold>]<jats:sup><jats:bold>–</jats:bold></jats:sup> and [<jats:bold>2</jats:bold>]<jats:sup><jats:bold>–</jats:bold></jats:sup> were prepared by reduction of <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> with decamethylcobaltocene. EPR spectra and DFT calculations reveal that the spin density is localized at the tpy–CO/Ru (tpy = terpyridine) site in [<jats:bold>1</jats:bold>]<jats:sup><jats:bold>–</jats:bold></jats:sup>, whereas it is centered at bpy–CO/Pt (bpy = 2,2′‐bipyridine) in [<jats:bold>2</jats:bold>]<jats:sup><jats:bold>–</jats:bold></jats:sup>. Efficient photoinduced electron transfer from triethanolamine to <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> is feasible by excitation at 500 nm [MLCT(Ru)].</jats:p>
