The present invention relates to an improved process for the preparation of ultrathin films of metal
phthalocyanines. The thickness of the films prepard by the process of the present invention is in the
range of 30 to 500 A. The films formed are useful for catalysts, sensors, solar energy conversions etc.
The various applications of such films could be catalysis for carbon dioxide photoreduction, solar
energy conversions, imaging technology, electronic devices, etc.
