Soluble precursors of 2,3-naphthalocyanine and phthalocyanine for use in thin film transistors

Soluble precursors of 2,3-naphthalocyanine (Nc) and phthalocyanine (Pc) were prepared and were converted into insoluble semiconducting thin films of Pc and Nc by heating after fabrication via spin-coating. The Royal Society of Chemistry.

The synthesis of metal-free phthalocyanines from phthalonitriles with hexamethyldisilazane

Metal-free phthalocyanines were prepared in good yields by heating phthalonitriles with hexamethyldisilazane, (NH4)2SO 4, and DMF. Good yields of metal-free phthalocyanines involving peripherally substituted phthalocyanines were attained with a catalytic amount of hexamethyldisilazane. Naphthalocyanine was also prepared. Additional additives were examined to accelerate the formation of the phthalocyanine framework.

Novel Synthesis of Metal-Free Phthalocyanines from Phthalimides and Phthalic Anhydrides with Hexamethyldisilazane

Metal-free phthalocyanines and their peripherally substituted derivatives have been synthesized from unsubstituted and substituted phthalimides, phthalic anhydrides, and naphthalimide on heating with hexamethyldisilazane under mild conditions.

PREPARATION, SPECTRAL PROPERTIES, AND X-RAY STRUCTURAL FEATURES OF 2,3-NAPHTHALOCYANINES.

We have prepared a series of 2,3-naphthalocyanine (H//2NPc) compounds and examined their spectroscopic properties. All of them can be vacuum sublimed as thin films which absorb strongly in the near infrared and thus make them potentially useful as optical data recording media. In addition, we have measured the electrical resistivities, at room temperature, of several of the compacted 2,3-naphthalocyanines and find them to be semiconductors. Doping with bromine vapor enhances the conductivities only slightly (H//2NPc actually becomes more resistive).
