Abstract

We have successfully obtained spin-coated films of unsubstituted planar phthalocyanines (free-base and copper phthalocyanine) from trifluoroacetic acid and chlorobenzene mixed solutions for the first time. The pre-annealed films did not consist of pure phthalocyanines; these films contained the solvent molecules. However, the residual solvent molecules could be removed by annealing at 425 K for 2 h in vacuum. This technique is useful for fabricating unsubstituted planar phthalocyanine thin films.
