Usage

Classification

Phthalocyanine salt, Hole-injection layer (HIL) materials, Light-Emitting Diodes, Organic electronics.

Applications

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.

Thermal characterization of doped polyaniline and its composites with CoPc

Thermal diffusivity of the composites of camphor sulphonic acid (CSA) doped polyaniline (PANI) and its composites with cobalt phthalocyanine (CoPc) has been measured using open cell photoacoustic technique. Analysis of the data shows that the effective thermal diffusivity value can be tuned by varying the relative volume fraction of the constituents. It is seen that polaron assisted heat transfer mechanism is dominant in CSA doped PANI and these composites exhibit a thermal diffusivity value which is intermediate to that of CSA doped PANI and CoPc. The results obtained are correlated with the electrical conductivity and hardness measurements carried out on the samples.

Boosting the Capacitive Performance of Cobalt(II) Phthalocyanine by Non-peripheral Octamethyl Substitution for Supercapacitors?

In this paper, pristine cobalt(II) phthalocyanine (CoPc) and non-peripheral octamethyl substituted CoPc (N-CoMe2Pc) are the focus of electrochemical investigation. CoPc and N-CoMe2Pc nanorods (NR) were synthesized by a facile precipitation process from sublimated bulk phthalocyanine powders and their electrochemical properties were explored. Due to the large specific surface area, the capacitance performance of the nanorods was significantly higher than that of the sublimated powder sample. N-CoMe2Pc powder exhibited better pseudocapacity compared with CoPc powder and CoPc NR, which is attributed to enhanced charge transfer rate and improved redox activity after the introduction of octamethyl substituents on phthalocyanine ring. The maximum specific capacitance value was achieved by N-CoMe2Pc NR based electrode, exhibiting 210.2 F g–1 capacitance at 5 mV s–1 scan rate and 156.1 F g–1 at 0.25 A g-1 current density, and also showing high efficiency and satisfactory retention. These results indicate that according to proper molecular design, N-CoMe2Pc NR could be applied as the potential candidate for electrode material in supercapacitors.

Preparation of Cobalt/Sulfur/Graphite Electrocatalyst for Oxygen Reduction from Efficient Two-Electron Pathway

Abstract—: Graphite, the most stable carbon allotrope, is widely used for various applications due to its interesting properties. In the present work, graphite surface has been partially oxidized by concentrated hydrochloric acid (37%); then, the graphite oxide surface has been modified by a low-temperature method using sulfur and cobalt atoms to obtain a Co–S–GC catalyst. The current density passing through Co–S–GC catalyst has been higher than that passing through graphite. The novel cobalt-based catalyst has been demonstrated good performance for oxygen reduction reaction (ORR) due to the unique bio-inspired structure. The number of electrons transferred for ORR vary from 2.17 to 2.41 in a wide range of over-potentials indicating an effective 2-electron pathway form O2 to H2O2. The Tafel slope (≈30 mV dec–1) indicates significant amount of cobalt oxide on the surface of the catalyst. The catalyst durability test displays a negative shift of only 11.7 mV after 10 000 cycles for its half-wave potential (E1/2).

Development of a perchlorate sensor based on Co-phthalocyanine derivative by impedance spectroscopy measurements

In this work, we have prepared a perchlorate sensor based on cobalt phthalocyanine derivative molecules. The membrane was deposited onto gold substrates using dip-coating method. Adhesion and morphological properties have been studied using contact angle measurements. Then, the sensitivity, the detection range and the detection limit were determined using electrochemical impedance spectroscopy (EIS) measurements. The sensor was also studied specificity towards interfering ions nitrate (NO3-), carbonate (CO32-) and sulfate (SO42-) to show the specificity of the membrane. The impedance behavior of the perchlorate sensor (gold/membrane) has been modeled by an equivalent electrical circuit using a modified Randles model for better understanding the phenomena present at the interface membrane/electrolyte.

An innovative light assisted production of acetic acid from CO2and methanol: A first photocatalytic approach using a reusable cobalt(ii) molecular hybrid at atmospheric pressure

Acetic acid is an important commodity chemical that is produced either by fermentation processes, or more commonly, through chemical routes such as methanol carbonylation with CO and H2, acetaldehyde oxidation, or hydrocarbon oxidation. More recently, methanol hydrocarboxylation with CO2 and H2 under thermal catalytic conditions has attracted interest. The synthesis of acetic acid from easily available CO2 is of great significance yet rarely reported. The present paper describes the first photocatalytic approach for the synthesis of acetic acid from methanol and CO2 under ambient reaction conditions without using molecular hydrogen. The maximum conversion of methanol achieved is 60% with a selectivity of 81% towards acetic acid using an octa-sulfur bound cobalt phthalocyanine (CoPc/S8) photocatalyst without an additional sacrificial electron donor. Product analysis, controlled experiments and DFT calculations suggest the formation of methylene carbene as a reactive intermediate. The developed methodology represents a potentially exciting approach for synthesizing acetic acid utilizing CO2 in a sustainable manner.

Preparation method and application of monosubstituent metal phthalocyanine derivative

The invention provides a method for preparing a monosubstituent metal phthalocyanine derivative. According to the method, the single-substituent metal phthalocyanine derivative is prepared by directlyand fully reacting a metal salt, an organic solvent and a nitrile organic compound and is used for efficient electrocatalytic carbon dioxide reduction. The method has the following advantages: on onehand, the method is simple, few impurities exist, and the atom utilization rate is high; and on the other hand, the problems of poor product selectivity, low yield and the like caused by complex substitution reaction, more side reactions, uncertain substitution positions and quantity and other factors in the traditional preparation method are avoided.
