A facile approach for the synthesis of an n-type π-conjugated hyperbranched polymer, namely hyperbranched polypyridinebenzene, is proposed based on the copolymerization of 1,3,5-tribromobenzene (BeBr 3 ) and 2,5-dibromopyridine via chain-growth condensation polymerization catalyzed by Ni(dppp)Cl 2 . The use of BeBr 3 as a branching unit simplifies the synthesis of n-type π-conjugated hyperbranched polymers, compared with a similar hyperbranched polymer prepared from 2,4,6-tribromopyridine (PyBr 3 ) and 2,5dibromopyridine requiring a lengthy synthetic route to give the starting material PyBr 3 . The results of UV-Vis spectroscopy and cyclic voltammetry suggest that our synthesized polymer retains its hyperbranched structure, which is beneficial in electrochemical doping.
