Synthesis and properties of a high dielectric constant copolymer of a copper phthalocyanine oligomer grafted to amino-capped polyimide

A novel high dielectric constant all-organic polymer film of a copper phthalocyanine oligomer grafted to polyimide (CuPc–PI) was successfully synthesized via a polycondensation between a copper phthalocyanine anhydride oligomer and amino-capped polyamic acid, followed by thermal treatment.
