Whereas nonsubsti-tuted phthalocyanines, mainly deposited by evaporation under vacuum, lead to polycrystalline films, it is possible to introduce hydrophilic and/or hydrophobic substituents on these molecules, which make them soluble in a wide range of solvents (15).
Studies about the deposition of metal phthalocyanines [26-31] have intensified in recent years, due to the prospects of creating new materials [32] with applications in electronics, for being an organic semiconductor [33, 34], optoelectronics [35], and in the developing of sensors with greater sensitivity and selectivity of gases and other products [36-40].
