Copper(II) phthalocyanine Structural

What is Copper(II) phthalocyanine?

Description

Copper(II) phthalocyanine, known as CuPc, has been used as an electron donor with fullerene-C60 or phenyl-C61-butyric acid methyl ester (PCBM) in vacuum-deposited organic photovoltaics (OPV). Power conversion efficiency of about 1% has been achieved [2] and improved efficiency of 4% with pentacene-doped CuPc layer. CuPc has also been used as a hole-injection material for light-emitting diodes. It has been reported that a thin CuPc layer may effectively enhance the hole injection from the anode to the emissive-polymer layer, resulting in a dramatic decrease in the operating voltage of the device. Device stability was achieved by depositing a copper phthalocyanine CuPc hole-injection layer HIL on the ITO anode.

Chemical properties

Copper(II) phthalocynaine (CuPc) is a metal phthalocyanine dye that acts as a p-type semiconductor. It has a charge mobility of 10-4 cm2/Vs. It forms a chemically stable thin film that exhibits photoconductivity and catalytic activity. A dark blue fine crystalline powder.

The Uses of Copper(II) phthalocyanine

Copper(II) phthalocyanine is a copper-complex dye. Copper(II) phthalocyanine is involved in studying 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 include OLED, OTFT, wearable display, and e-paper.

What are the applications of Application

Copper(II) phthalocyanine, known as CuPc, has been used as an electron donor with fullerene-C60 or phenyl-C61-butyric acid methyl ester (PCBM) in vacuum-deposited organic photovoltaics (OPV). Power conversion efficiency of about 1% has been achieved [2] and improved efficiency of 4% with pentacene-doped CuPc layer.
CuPc has also been used as a hole-injection material for light-emitting diodes. It has been reported that a thin CuPc layer may effectively enhance the hole injection from the anode to the emissive-polymer layer, resulting in a dramatic decrease of operating voltage of the device. Device stability was achieved by depositing a copper phthalocyanine CuPc hole-injection layer HIL on the ITO anode. The improved stability could be contributed to the good match of its highest-occupied molecular orbital (HOMO) level to the work function of ITO, and the improved wetting property of organic materials on ITO. Moreover, CuPc has very weak absorption of light, with wavelengths from 400 to 500 nm, making it suitable for use in blue and green OLEDs.
Effective electron-blocking was also observed for inorganic–organic hybrid perovskite solar cells when CuPc-doped spiro-OMeTAD was used as the hole-transporting layer.
