This invention belongs to the field of organic and polymer synthesis technology, specifically relating to a method for synthesizing polynaphthalene-phenanthrene ether polymers. In the field of polymer synthesis methodology, condensation polymerization is a common polymerization method. This method typically uses functional groups to participate in the polymerization reaction. The introduction of functional groups not only increases the cost of monomer synthesis but also leads to storage difficulties due to their reactivity issues, requiring the addition of end-capping reagents at reaction termination. Therefore, developing C-H bond condensation polymerization methods is of great significance. This invention proposes an oxidative polymerization method for naphthalene-phenanthrene ether monomers. This method uses polycyclic aromatic hydrocarbons naphthalene and phenanthrene as C-H bond donors, and selective oxidative coupling polymerization of the naphthalene-phenanthrene backbone structure can be achieved by controlling the oxidant and solvent conditions to obtain polynaphthalene-phenanthrene ether (see abstract figure). The polymer obtained by this method exhibits good thermal stability and a high glass transition temperature, as tested by DSC and TGA, possessing the performance characteristics of high-performance engineering plastics.
