High frequency dielectric response in a branched phthalocyanine.
We describe the dielectric effects in a novel branched phthalocyanine system. The synthesis and characterization of the hyperbranched structure are provided. The dielectric constant was approximately 45 over many decades of frequency, and the dispersion was small up to 1 MHz. The losses experienced in this novel material were very small (close to 0.001) at high frequency. The mechanism of this novel effect in the branched structure involves a delocalized polaronic state which takes advantage of the strong intramolecular interactions in the system.
