A new hyperbranched zinc phthalocyanine ( ZnPc) is prepared. The dielectric properties and thermosta-bility are studied by using dielectric spectra and differential scanning calorimetry ( DSC ) . Hyperbranched zinc phthalocyanine ( ZnPc) dendritic system with high dielectric constant and very low dielectric loss is investigated. A high dielectric constant (15) is obtained:it is larger than most of the existing polymer materials. The dielectric loss is lower than 0. 002 at a high frequency. Both the dielectric constant and dielectric loss display very small disper-sion. It is believed that the Pc system with a new, branched structure can be applied in future high-technology fields such as high energy density storage devices, embedded capacitors, and pulsed capacitors, etc.
