Abstract

Three hyperbranched copper phthalocyanine (HBCuPc) oligomers based on biphenyl segments have been successfully synthesized. Rigid rod semiconductor material with good solubility, small dispersion of the dielectric constant, and low dielectric loss was obtained by solution suspension. The content of the CuPc unit in HBCuPc was increased by increasing the prepolymerization time from 12 h to 36 h. The dielectric loss was slightly influenced by temperature but remained stable below 100°C. Furthermore, the obtained novel HBCuPc materials have potential for applications as organic dielectric materials.
