Synthesis and structure of high-quality films of copper polyphthalocyanine – 2D conductive polymer

We propose an experimental approach, by which thin films of copper polyphthalocyanine (CuPPC) can be directly synthesized in a chemical vapor deposition (CVD) set-up at mild temperature (420 °C). High polymerization degree and high crystallinity of the films was confirmed by TEM, FTIR and UV-VIS studies; the stacking structure of CuPPC layers was determined, inter-layer spacing was estimated from XRD and TEM electron-diffraction. Quantum-chemical study performed providing support for experimental structure determination and yielding information on the electronic structure.
