Paper Abstract

Phthalocyanine dyes with various central metal atoms and different substituents showing improved spectroscopic properties to match the output of GaAs diode-laser have been synthesized. Smooth thin films have been prepared by spin- coating technique. Solvent-vapor induced crystallization of VOPc(OC3H7)4 has also been studied. The results showed that the VOPc(OC3H7)4 primarily deposited on glass substrate as an amorphous form. However, the dyes were changed to crystalline form by exposure to appropriate solvent vapors. The polymorphs of the VOPc(OC3H7)4 were investigated by visible absorption and IR spectroscopy, X-ray diffraction and high resolution electron microscopy. The optical recording performances of the thin films were also reported.
