The effect of organic solvents on the optical and morphological properties of metallophthalocyanines containing 3,5-bis(2 ′,3 ′,4 ′,5 ′,6 ′-pentafluorobenzyloxy)benzyloxy groups

Thin films of metal phthalocyanines (M: Co, Zn, Ni) substituted with four 3,5-bis(2′,3′,4′,5′,6′-pentafluorobenzyloxy)benzyloxy groups have been prepared by the spin-coating technique. Optical properties and surface morphology of the thin films of metallophthalocyanines have been investigated as a function of organic solvents of acetone, chloroform, tetrahydrofuran, dimethylformamide and dimethylsulfoxide. Results show that optical properties and surface morphology of the prepared films depend on the type of organic solvent used.
