摘要

We report the preparation of multi-component molecules based on carotene-substituted 2, 2′: 6′, 6 ″-terpyridine ligands. The synthetic protocol based on a double Wittig-Homer coupling reaction uses 4′-methyldiphenylphosphinoxide-2, 2′: 6′, 2 ″-terpyridine and the relevant carotene bisaldehyde. The all-trans conformation of the double bonds is confirmed by proton NMR. Highly colored and redox-active ruthenium (II) dinuclear ...
