1H NMR;  oxidative coupling polymerization;  aromatic molecules;  Connection method

Five copolymers containing homotetraluene, p-dihexyloxybenzene, anthracene, fluorene, N-ethylcarbazole and trans-pstyrene were prepared by oxidative coupling polymerization. The 5H NMR spectra of these copolymers were tested, and the 1H NMR signals of other monomers were attributed by using the special structure of homotetraluene, focusing on the connection mode of these aromatic molecules in oxidative coupling polymerization. The conclusion is basically consistent with the oxidative coupling polymerization mechanism.
