Synthesis and Characterization of Ferrocene-Containing Hyperbranched Poly(aroylarylene)s
Authors/Creators
Description
Ferrocene-containing hyperbranched poly(aroylarylene)s are prepared in satisfactory yields by one-pot copolycyclotrimerization of bis(aroylacetylene)s with a ferrocene-containing monoyne. The ferrocene content of the polymers can be varied by changing the monomer feed ratio, and copolymers with up to 41 mol% of ferrocene moiety can be readily prepared. All the polymers are thermally stable, losing little of their weights when heated to 340 °C.
