3.9 1 ! 3 PHTHALOCYANINE-BRANCHED MONOMERS
The condensation of 4-nitrophthalonitrile and 4-(2-dimethylaminoethylsulfanyl)-
phthalonitrile, then reduction of the nitro group gave the corresponding monoamine,
which was quaternized with MeI to give 2-amino[tris((2-dimethylaminoethylsulfa-
nyl)phthalocyanine)triiodide] hydrochloride [159].
