The self‐assembly of an amido‐ended hydrophilic hyperbranched polyester (HTDA‐2) into ordered, compact, 2D, tree‐like structures with a diameter of over 500 μm and a trunk‐width of about 3–5 μm by the induction effect of cupric ions is presented. Influencing factors on the morphology of the self‐assemblies, including temperature, time, solvents, concentration, and humidity, investigated by polarizing optical microscopy (POM) and scanning electron microscopy (SEM), are discussed. The self‐assembly mechanism is analyzed by X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), SEM, and Fourier transform IR (FTIR) spectroscopy. A dimension ( D f ) of about 1.50 for the perfect fractal behavior and the crystal behavior of the self‐assemblies are determined.
