Copper(II) phthalocyanine are involved in the study of photosensitizer chemistry for uniform polymerization, luminescence chemistry and spectrophotometric analysis, organic synthesis and polymerization. This pigment is used in enamels, linoleum, inks, plastics, and rubber goods. Photoisomerizable phthalocyanines are used in rewritable CD or DVD printing.?Other applications in organic solar cells, biosensitizers and display devices such as OLED , OTFT, Wearable Display, and e-paper.
