Abstract

We describe an improved synthetic approach to access tripodal compounds with variable footprints and anchor groups. Two ruthenium(II) bipyridine tripodal complexes with three carboxylic acid groups in meta (Ru-m-COOH, 1) and para (Ru-p-COOH, 2) positions, and with large (180-250 Å²) footprints were synthesized and bound to the surface of nanostructured TiO₂. Selected properties of 1 and 2 in solution and bound are reported.
