Usage

General Description

Phthalocyanine lead is a synthetic chemical compound that is commonly used as a blue pigment in a variety of applications including paints, inks, and plastics. It is derived from phthalocyanine, a heterocyclic compound that contains four nitrogen atoms and a central metal ion, in this case lead. Phthalocyanine lead is known for its high color strength, durability, and resistance to light and heat, making it a popular choice for coloration in industrial and artistic materials. However, due to its lead content, there are concerns about its toxicity and environmental impact, and as a result, alternative pigments are being sought for use in consumer products.

UV-visible spectral study on the stability of lead phthalocyanine complexes

UV-visible electronic spectral study has been done on lead phthalocyanine (PbPc), lead tetranitro phthalocyanine (PbTNP) and lead tetraamino phthalocyanine (PbTAP) in dimethyl sulphoxide (DMSO) and H2SO4 media. Metal free phthalocyanine (H2Pc) is insoluble in DMSO and soluble in conc. H2SO4. The study has been extended to H2Pc to compare the stability of phthalocyanine structure with the PbPc complexes in H2SO4 medium. PbPc complexes are stable in DMSO, and all the complexes are more stable in 36 N H2SO4 than in 30 N and 28 N H2SO4 media. Further, complete demetallation and degradation of the phthalocyanine structure have been observed for all the PbPc complexes in 36 N H2SO4 medium within a week's time. The stability of these complexes is compared with H2Pc in H2SO4 medium. The decomposition reactions in H2SO4 media for H2Pc, PbPc, PbTNP and PbTAP are followed spectrophotometrically and rate constants were calculated. The decomposition reactions were found to follow the first-order kinetics with respect to the concentration of their respective phthalocyanine derivatives.

Ohmic and space-charge-limited conduction in lead phthalocyanine thin films

The electrical characteristics of thermally evaporated triclinic lead phthalocyanine thin films are studied. A number of parameters is evaluated on the basis of the theory of space-charge-limited conduction and the following values are obtained: permittivity ε = 3.16 × 10-11 F m-1; hole mobility μ ≈ 6.05 × 10-10 m2 V-1 s-1; room temperature hole concentration po ≈ 1.60 × 1018 m-3; concentration of traps per unit energy range at the valence band edge Po ≈ 2.79 × 1043 J-1 m-3; temperature parameter of trapping distribution Tt ≈ 770 K; total trap concentration Nt ≈ 2.97 × 1023 m-3. The room temperature electrical conductivity σ = 1.55 × 10-10 S m-1. C-U measurements confirm that the Au-PbPc interface does not form a Schottky barrier. At low temperatures the capacitance of Au-PbPc-Au devices is temperature insensitive, increasing rapidly above 300 K and saturating at about 400 K. Measurements of thermoelectric power confirm that semiconduction is p-type.

Low-temperature synthesis of phthalocyanine and its metal complexes

Conditions for synthesizing unsubstituted phthalocyanine and its metal complexes from phthalonitrile at low temperatures (0-50°C) are optimized. Phthalocyanine and phthalocyaninates are produced under these conditions using activated Rieke metals, metals on inert substrate, sources of soluble metals in the form of unstable metal complexes, zeolites, solid-phase electrosynthesis of phthalonitrile, and UV irradiation. The use of pyrophoric metals is found to be the most efficient due to a large number of defects in their structure favoring the initial stage of phthalonitrile cyclization on a metal matrix. The suggested mechanism of formation of phthalocyanine macrocycle assumes participation of metal agglomerates occurring in activated metals. Pleiades Publishing, Inc., 2006.
