Abstract

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 TiO₂ and insulating ZrO₂ nanoparticle films.
