  • Phthalocyanines and Some Current Applications

    Jun 21, 2017Since their initial accidental synthesis and characterization in Scotland in the late 1920s, there has been a strong research focus on the use of phthalocyanines (Pcs) as dyes and pigments. In recent years, active research fields have included their use in electrophotography, photovoltaic and solar cells, molecular electronics, Langmuir-Blodgett films, photosensitizers, electrochromic display

  • 3.4 Green

    3.4.4 Phthalocyanine Green Phthalocyanine green (G10 - G11) is similar to phthalocyanine blue, but absorbs more strongly in the short NIR. Hence, the NIR reflectance of a thin phthalo green film over white, while respectable, is only 70% of that achieved by a thin layer of phthalo blue over white (0.45 for G10 vs. 0.63 for U12).
