What is it about?
Metalla-aromatic conjugated polymers have been produced for the first time by a novel polymerization reaction. This metal-involved triple bond polymerization (MTP) reaction has the advantage of efficiency, specificity, and feasibility. The resulting polymers are not only soluble and stable but also show broad and strong absorption in the UV-Vis region. The insertion of metals was demonstrated to produce the unique dπ-pπ conjugation polymer systems.

Why is it important?
The metalla-aromatic ring is a new kind of aromatic ring in which a transition metal is involved in an aromatic framework. In comparison to the traditional conjugated polymers that use p orbitals in π-conjugation (i.e., pπ-pπ conjugation) , the incorporation of metalla-aromatics into conjugated polymers enables the use of d orbitals for π-conjugation, affording dπ-pπ conjugated systems. Thus, the inclusion of metalla-aromatic building blocks into conjugated polymer skeletons is a promising method to construct novel polymer structures. To the best of our knowledge, such metalla-aromatic conjugated polymers have not been reported to date.
