“…Applications for these include in the fields of catalysis, pigments, dyes, sensors, liquid crystals, donor–acceptor systems, nonlinear optics, and optically induced storage materials. , A high degree of surface coverage can be expected from the planar structured phthalocyanines, and hence, an increased efficiency of corrosion inhibition can be obtained . Phthalocyanines are more environmentally friendly − and strongly adhere to the surface as compared to commercially available, nongreen corrosion inhibitors for copper surfaces. Also, in addition to their effective corrosion inhibition properties, phthalocyanines are benign, cost-effective, easily manufactured, easily tunable, stable, and chemically inert.…”
