  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 {\deg}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.
