Abstract:
A chemical composition comprising the formula: wherein when z is 0, then A is selected from the group consisting of metallocenylethynyl, and phenylethynyl; wherein when z is 1, s is 0, and m is 1, then A is selected from the group consisting of metallocenylethynyl and phenylethynyl; wherein when z is 1, s is 1, and m is 1, then A is selected from the group consisting of H and phenylethynyl; wherein when z is 2, s is 0 in the repeating unit adjacent to A, and m is 0 in the repeating unit adjacent to A, then A is selected from the group consisting of H and phenylethynyl; wherein when z is 2, s is 0 in the repeating unit adjacent to A and m is 1 in the repeating unit adjacent to A, then A is selected from the group consisting of metallocenylethynyl and phenylethynyl; wherein when z is 3, s is 0 in the repeating unit adjacent to A, and m is 1 in the repeating unit adjacent to A, then A is selected from the group consisting of metallocenylethynyl and phenylethynyl; wherein in all other cases A is selected from the group consisting of H, metallocenylethynyl, and phenylethynyl; wherein M is a metal selected independently from the group consisting of Fe, Mn, Ru, Co, Ni, Cr and V; wherein Rx is independently selected from the group consisting of an aromatic, a substituted aromatic group and combinations thereof; wherein Ry is independently selected from the group consisting of an aromatic, a substituted aromatic group and combinations thereof; wherein m is &gE;0; wherein s is &gE;0; wherein z is &gE;0; and wherein m and s are independently determined in each repeating unit.
