A metal-free purple H2Pc single crystal was synthesized by a facile solvothermal method, and its solubility and near-infrared (NIR) optical properties were also investigated due to its potential applications as a light-emitting layer for OLEDs. The H2Pc single crystal is insoluble in 1-chlorine naphthalene and other organic solvents. It gives a wide absorption in the range from 620 nm to 679 nm and a wide emission in near 922 nm. As an active light-emitting layer, H2Pc was employed to fabricate electroluminescent (EL) devices with a structure of ITO/NPB (30 nm)/Alq3:H2Pc (30 nm)/BCP (20 nm)/Alq3 (20 nm)/Al. The emission center is at 936 nm when the H2Pc doping concentration is 20 wt%. The doping concentration strongly governs the emission intensity. When doping concentration decreases from 10 wt% to 1 wt%, the emission intensity remarkably fades, and simultaneously the emission center undergoes a blue shift.

Synthesis of Novel Unsymmetrical Monoaminated Phthalocyanines
Sastre, Angela,Torres, Tomas,Hanack, Michael
, p. 8501 - 8504 (1995)
Metal-free monoaminophthalocyanine 3 was synthesised by reacting of subphthalocyanine 1 with 5-amino-1,3-diiminoisoindoline 2.Alternatively, compound 3 was prepared from octadecylaminodiiminoisoindoline 6 by reaction with 1 to give 7 followed by acidic hydrolysis.The zinc complex 8 was obtained from 3 by treatment with anhydrous zinc acetate.The preparation of 8 by template condensation of subphthalocyanine 1 with aminodiiminoisoindoline 2 and zinc acetate was unsuccessful.In this case, a mixture of statistical distribution compounds was obtained.A tentative reaction pathway for the condensation between subphthalocyanines and diiminoisoindolines is also given.

A new family of cationic phthalocyanines containing four guanidinium groups was synthesized in pyridine-HCl at 120 °C; under these conditions zinc was removed from both the starting materials and products to reveal a new synthetic route to metal-free phth

A convenient, fast, efficient, and ecofriendly synthesis of metal-free phthalocyanines from various substituted phthalonitriles in different hydroxyalkylammonium ionic liquids in the presence of 1,8-diazabicyclo-[5,4,0]- undec-7-ene (DBU) is reported in moderate yields. The effect of concentration of DBU and temperature on the synthesis of phthalocyanine in N-(2-hydroxyethyl)-N, N-dimethylbutylammonium bromide ionic liquid has been examined, and the ionic liquid has been recovered and reused conveniently.

The results of the kinetic study of dissociation of Gd(III) and Dy(III) complexes with phthalocyanine of the composition (X)LnPc (X is single-charged acido ligand) with isolation of macrocyclic ligand depending on the temperature, composition of mixed eth
Cerium-promoted formation of metal-free phthalocyanines
Lee, Chi-Hang,Ng, Dennis K.P
, p. 4211 - 4214 (2002)
Treatment of phthalonitriles with 6 mol% of CeCl3 or Ce(acac)3 (acac=acetylacetonate) in refluxing 1-pentanol affords the corresponding metal-free phthalocyanines in moderate yields. This non-alkaline pathway is complementary to the base-promoted cyclization methods which are commonly employed in the synthesis of phthalocyanines. Addition of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) greatly shortens the reaction time and increases the yield of these reactions.
Nanostructural catalyst: Metallophthalocyanine and carbon nano-onion with enhanced visible-light photocatalytic activity towards organic pollutants
Brzezinski, Krzysztof,Butsyk, Olena,Chaur, Manuel N.,Czyrko-Horczak, Justyna,Echegoyen, Luis,Olejnik, Piotr,Plonska-Brzezinska, Marta E.,Regulska, Elzbieta,Tomczykowa, Monika,Zubyk, Halyna

Metallophthalocyanine (MPc) and carbon nano-onion (CNO) derivatives were synthesized and characterized by using ultraviolet-visible spectroscopy, infrared and Raman spectroscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy and X-ray powder diffraction. The unmodified CNOs and MPc-CNO derivatives were used as photocatalysts for rhodamine B (RhB) degradation under visible-light irradiation. The photocatalytic studies revealed that the MPc-CNO nanostructural materials simultaneously exhibited a high absorption capacity and an excellent visible-light-driven photocatalytic activity towards RhB. These nanostructures possess great potential for use as active photocatalysts for organic pollutant degradation.

In this paper, tosylated 4-morpholinoaniline units fused peripherally tetra-substituted free-base (5), copper(II) (6), zinc(II) (7), cobalt(II) (8) and magnesium(II) (9) phthalocyanines (Scheme 1) were reported and these new phthalocyanine conjugates were characterized through Fourier Transform–Infrared (FT–IR) with ATR sampling accessory, Mass Spectra Analysis [Matrix Assisted Laser Desorption/Ionization–Time of Flight–Mass Spectral (MALDI–TOF–MS)] and Ultraviolet–visible (UV–vis) (for all new phthalocyanines), elemental analysis, as well as 1H and 13C NMR spectroscopic techniques [for the compounds (2), (4), (5), (7) and (9)]. The potential utilization of the new peripheral phthalocyanine compounds (7–9) as the new pharmaceutical agents in PDT applications (in oncology and molecular biology) were determined in aspects of pBR322 plasmid DNA cleavage on agarose gel electrophoresis. The results showed that compound (7) cleaved pBR322 plasmid DNA with irradiation. Compound (7) displayed hypochromism without any shift on the addition of increasing concentrations of ct-DNA and Kb of compound (7) was calculated as 2.45 ± (0.20) × 104 M?1. In photochemical studies, the ΦΔ value of compound (7) was determined as 0.11. The cytotoxic/phototoxic properties of compound (7) which had the best photocleavage effects among tested compounds were investigated using MTT assay toward human colorectal (HCT-116) and cervical (HeLa) cancer cells. The cell viabilities of compound (7) were found to be 73 ± 1.6% (HCT-116) and 65 ± 5.5% (HeLa) at 100 μM with irradiation.
