compound 1 was prepared by the treatment of 4-nitro-1,2-dicyanobenzene with 2-aminothiophenol.

The molecular ion peak for 1 was observed at 292 m/z in its GC-MS spectrum which verified the formation of this phthalonitrile
It was desirable to modify the structure of the phthalonitrile
monomer or add diluents to lower the melting temperature [12-16].
As described by Hu and Hornbuckle, the process commonly used to produce these blues and greens involves phthalic anhydride, urea, or phthalonitrile
and a copper or copper salt, which are then processed using an organo-chlorine solvent such as di- or trichloroben-zene.
The method is comprised of a step of obtaining a mixture by mixing at least one compound selected from the group of phthalonitrile
derivative, isoindoline derivative and subphthalocyanine derivative, and a compound supplying copper or titanium with a solvent; and a step of holding the mixture at not less than a temperature where a subcritical state or a supercritical state of the solvent occurs to obtain the pigment by reacting the compounds.
Our synthesis of the dyes involved making and purifying a precursor, a phthalonitrile
, and using it to synthesize a Pc.
 fabricated modified CNT with phthalonitrile
groups (CNT-CN) and used it as additive in preparing PEN-based composites.
resins are an unique class of high-temperature materials having a variety of potential uses in composite matrices, films, adhesives, and electrical conductors because of their outstanding mechanical properties, excellent thermal and thermo-oxidative stability, and fire resistance, etc.
The common method to synthesize substituted phthalocyanines is to prepare the phthalonitrile
with required substituents then synthesize the corresponding phthalocynines by cyclotetramerization of the substituted phthalonitrile
