Phenylated polyphenylenes based on 4,4'-diethynylbenzophenone
Phenylated polyphenylenes were synthesized by the Diels-Alder reaction carried out under mild conditions using 4,4′-diethynylbenzophenone as a dienophilic component. It was shown that the synthesized polyphenylenes combine high thermal stability and good solubility in DMF, DMSO, dioxane, chloroform, and toluene.
