Solvents that are used for the manufacture of thin films should has a low boiling point. In toluene it is high. Acetone can be used. If you are using toluene, dried samples must under vacuum

Elie Nadal

Thank you, I will try Toluene, or THF. Does anyone have more information about the physical and chemical properties of the PAZO? Spin-coatting recipes?
