Polymerizable diazonium salts having redox properties and absorption in the visible range, a process for preparing them and uses thereof are disclosed. The salts have the general formula: n [X X+ L n D d E m (N 2 + ) p ][(B − ) p+x ] n in which:n X is chosen from transition metals, preferably X is chosen from ruthenium (Ru), osmium (Os), iron (Fe), cobalt (Co) and iridium (Ir), x is an integer ranging from 1 to 5 inclusive, L is a ligand chosen from pyridine, bipyridine, terpyridine, phenanthroline and phenylpyridine groups, and mixtures thereof, n is an integer ranging from 1 to 5 inclusive, D is a saturated or unsaturated, C 1 -C 5 alkyl spacer compound, d=0 or 1, E is an aromatic or polyaromatic spacer compound that can contain one or more heteroatoms, m is an integer ranging from 0 to 5 inclusive, p is an integer, and B is a counterion. |
