Synthesis of Highly Insulated Conjugated Metallopolymers Containing Terpyridine–Metal Complexes
Access this Article
A bridging monomer with terpyridine moieties at both ends of the insulated conjugated chain was successfully synthesized. The synthesis necessitated a new strategy, in which Fe<sup>II</sup> was employed as a removable water-solubilizing substituent. The monomer was able to coordinate with Fe<sup>II</sup>, Co<sup>II</sup>, Ni<sup>II</sup>, or Ru<sup>II</sup> to give highly insulated conjugated metallopolymers. The high-coverage insulation suppressed the recombination of charge carriers relative to an uninsulated reference and provided higher charge mobility along the chain than the less insulated metallopolymer.
