Cobalt phthalocynine (CoPc) is a member of metal phthalocyanines (MPcs) are frequently used in many organic electronic devices such as light-emitting diodes (LEDs), organic photovoltaics (OPVs), organic field-effect transistors (OFETs) and chemical sensors as a p-type semiconducting material. Compared to other hole-injection layer (HIL) materials, most metal phthalocyanines are water and air stable, thermally stable, and nontoxic. They can be sublimed or sputtered with highly uniform, thin films on a variety of substrates. The synthesis of such materials are also relatively inexpensive and easy to prepare. The chemical structure of MPc allows tuning of its ionisation potential or HOMO levels by altering the central atom in Pc macrocycles.
Using cobalt phthalocyanine (CoPc) layer as a hole-injection layer (HIL), remarkable improvements in turn-on voltage and luminance have been observed in organic light-emitting diodes (OLED) [1, 2, 3, 4]. The driving voltages of the MPc electroluminance devices are found to decrease in the order of:
ZnPcwhich is in agreement with the order of HOMO levels of MPcs.

Cobalt(II) phthalocyanine may be used to develop carbon black based electrocatalysts. CoPC may be used as an end capping agent of a hyperbranched poly(aryl ether ketone) to be used for oxidative decomposition of 2,4,6,-trichlorophenol. CoPC modified carbon paste may be used as indicators for electrocatalytic amperometric measurements. ZnO impregnated with CoPC may be used as a sensitizer to determine the photodegradation of cyanide in aqueous suspension. CoPC catalyzed aerobic regenerations of aldehydes and ketones have been investigated.
Cobalt(II) phthalocyanine (CoPC )is a metallopthalocyanine.
