Summary: We developed a facile approach to hyperbranched polymers by applying a superelectrophilic reaction within an A 2 + B 3 strategy. A significant reactivity difference between the intermediate and the starting material was utilized to avoid gelation in the A 2 + B 3 polymerization. A number of hyperbranched poly(arylene oxindole)s were achieved in a one‐step polymerization and characterized by NMR spectroscopy and gel permeation chromatography. Moreover, further modifications at the interior and exterior of the resulting polymers were explored as well.Structure of the hyperbranched polymers produced using the A 2 + B 3 approach.
