<p>The present invention relates to electrochromic polymers, obtained by polymerization of monomers. The present invention further relates to monomers of general formula (I) or (II), wherein A and B are specific functional groups selected among the following: -C=0, -C=S, - 0(C=0), -0(C=S), -0(C=0)0, -(C=0)0, -(C=S)0, -(C=S)S, -(C=0)N, -(C=S)N, -SO, - S02, or, as an alternative, any linear or branched alkylic chain or a glycolic chain; wherein R and R' are linear or branched alkylic chains or glycolic chains, and wherein W is a monodisperse electrochromic derivative of general formula (III), wherein Het-1 and Het-2 are specific heterocyclic groups, and wherein pi represents one of the following: a double bond, a triple bond or a plurality of double or triple bonds conjugated in a number n, n being equal to 2 or 3 or, for example, a benzenic ring or a thiophenic ring; X represents one of the following elements: O, S, Se; wherein R2, R3 and R4 are substituents; and wherein m is equal to 0, 4, 5 or 6. The present invention also relates to electrochromic panels and electrochromic ophthalmic lenses, comprising polymers in accordance with the present invention.</p> |
