Homoleptic Ru II complexes carrying rigid linkers for attachment to semiconductor surfaces were synthesized by using the click reaction. Star‐shaped complexes KStar‐TzC‐pBn ( 1a ) and KStar‐TzC‐Ipa ( 1b ), composed of 2,2′‐bipyridine ligands 4,4′‐disubstituted with 1,2,3‐triazole rings connected to the Ru complex through the C4 of the 1,2,3‐triazole (Tz) ring and capped with p ‐benzoic (pBn) and isophthalic (Ipa) methyl esters, respectively, as well as KStar‐TzN‐pBn ( 1c ), connected to the Ru complex through the N1 of the Tz ring, were studied in solution and bound to semiconducting TiO 2 and insulating ZrO 2 nanoparticle films.
