Multi-layer preparation of phthalocyanine dye and diazonium resin using a self-assembly fabrication method

Abstract

By using the electrostatic self-assembly technique, arranged multi-layer thin films composed of diazonium resin as the polycation and phthalocyanine as the anion, were alternately fabricated on a glass slide. The obtained multi-layers were characterized by UV-vis spectroscopy and Atomic Force Microscopy (AFM). The growth of multi-layers formed by the sequential alternative adsorption of diazonium resin and phthalocyanine was observed and determined. The results of UVvis absorption show that the deposition process is progressive and uniform. In addition, AFM images of the self-assembled multi-layer films reveal that the surface of the films is relatively uniform.

Screen-Printed Electrodes Modified with Metal Phthalocyanines: Characterization and Electrocatalysis in Chlorinated Media

“…About 70 different metals [ 1 ] can be used as the central ion, opening new gates in the generation of phthalocyanines with tunable properties. Their excellent thermal and chemical stability as well as their outstanding optical properties turn them into very promising materials for a huge variety of applications such as preparation of dyes and pigments [ 2 ], optical devices [ 3 ], solar cells [ 4 ], gas sensors [ 5 ], optical data storage [ 6 ], electrochromic devices [ 7 ], electrocatalytic applications [ 8 , 9 ] and biosensors [ 10 ].…”
