Summary. Unsymmetric metallophthalocyanines (M=Zn, Co, Ni) carrying alkylthio and acetyloxyethylthio groups on peripheral positions were prepared from 4,5-bis-alkylthio-phthalonitrile, 4,5-bis-(acetyloxyethylthio)-phthalonitrile, and the corresponding anhydrous metal salts Zn(CH3COO)2, NiCl2, and CoCl2. The extremely soluble compounds were characterized by their IR, 1H NMR, and UV/Vis spectra. Their long wavelength absorption band was found to be bathochromically shifted; their solubility
is superior to that of symmetrical phthalocyanines.

Metal phthalocyanines (M = Cu, Ni, Co) 3-5 bearing four 16-membered diazadithia macrocycles at the peripheral positions were prepared. Detosylation with concentrated sulfuric acid afforded products containing both sulfonated groups on the aromatic rings of the macrocyclic substituents which are excellently soluble in water and donor sites for binding four CuII ions to give a pentanuclear complex. 相似文献

The synthesis and characterization of A3B-type phthalocyanines, ZnPc1–4, bearing bulky 2,6-diisopropylphenoxy-groups or chlorine atoms on isoindoline units “A” and either one or two carboxylic anchors on isoindoline unit “B” are reported. A comparison of molecular modelling with the conventional time dependent—density functional theory (TD-DFT) approach and its simplified sTD-DFT approximation provides further evidence that the latter method accurately reproduces the key trends in the spectral properties, providing colossal savings in computer time for quite large molecules. This demonstrates that it is a valuable tool for guiding the rational design of new phthalocyanines for practical applications. 相似文献

The new metal-free phthalocyanine 5 and phthalocyaninatometals 6–8 (M=Co, Ni, or Zn) fused in peripheral positions with four 13-membered tetrathiamacrocycles were prepared by cyclotetramerization of 2, 3, 6, 7, 9, 10-hexahydro-5H-[1, 4, 8, 11]benzotetrathiacyclotridecine-13, 14–dicarbonitrile in the presence of a suitable metal salt or a strong organic base. In contrast to the aza- or oxamacrocycle-fused analogs, the solubility of these phthalocyanines is very low. Complexation of the tetrathiamacrocycles of 7 and 8 with PdII or AgI to form pentanuclear products was accomplished from their suspensions. 相似文献

In this study, 4‐{2‐(2‐thienyl)ethoxy}phthalonitrile ( 3 ) and its tetra substituted peripherally metal‐free ( 4 ), lead (II) ( 5 ), magnesium (II) ( 6 ), and cobalt (II) ( 7 ) phthalocyanines were synthesized. The structural characterization of the obtained compounds was performed by a combination of FTIR, 1H‐NMR, UV–vis, and MALDI‐TOF techniques. The inhibitory properties of these compounds were determined using Ingkaninan's methods against cholinesterase enzymes. Compound ( 7 ) had the highest enzyme inhibitory effect toward AChE and BuChE enzymes with IC50 values of 23.71 ± 0.39 and 27.29 ± 0.22 μM, respectively. The enzyme kinetic study of compound ( 7 ) demonstrated noncompetitive AChE inhibition and uncompetitive BuChE inhibition. The Ki values of compound ( 7 ) against AChE and BuChE were found to 39.15 and 7.25 μM, respectively. In the tested compounds, ( 7 ) deserves further investigation for potential therapeutic candidates of Alzheimer's disease. 相似文献

Lanthanide heteropoly compounds K15[Ln(HSiW9O34)2]·28H2O(Ln = La, Ce, Nd), denoted as Ln(SiW9)2, were synthesized and characterized by element analysis, TG-DTA, IR, UV, XPS and XRD. The results show that partial oxygen in Ln(SiW9)2 was coordinated with Ln3- , where Ln-3 was in the inner side of the heteropoly anions, while the fundamental structure of SiW9 had little change. The result was supported by ion exchange experiment. 相似文献

Summary. A novel metal-free phthalocyanine and its nickel(II) and copper(II) phthalocyaninato complexes were prepared. The new compounds
were characterized by elemental analyses, 1H- and 13C-NMR, IR, UV-Vis, and mass spectral data. The NMR and/or UV-Vis spectra of these compounds showed extremely broad bands and/or
peaks. This phenomenon seems to be related to the presence of the sulfur substituents, which is consistent with the data observed
for similar compounds. The absorption spectra of these compounds were greatly affected by aggregation processes.

In this study novel peripherally tetra 1,3-diethoxy-2-propanol substituted Co(II), Cu(II), Mg(II), Ni(II) Zn(II) phthalocyanine derivatives were prepared. The characterization of the novel compounds was made by FT-IR, 1H-NMR, UV-vis and MALDI-TOF mass. Electrochemical, in-situ spectroelectrochemical and electrocolorimetric measurements have been carried out with the aim to determine the redox properties, to illuminate reaction mechanism and the effect of substituent and metal center. Moreover, the color properties and aggregation tendency of compounds were also investigated. 相似文献

The pentafluorosulfanyl (SF5) group is more electronegative, lipophilic and sterically bulky relative to the well‐explored trifluoromethyl (CF3) group. As such, the SF5 group could offer access to pharmaceuticals, agrochemicals and optoelectronic materials with novel properties. Here, the first synthesis of phthalocyanines (Pcs), a class of compounds used as dyes and with potential as photodynamic therapeutics, with a SF5 group directly attached on their peripheral positions is disclosed. The key for this work is the preparation of a series of SF5‐containing phthalonitriles, which was beautifully regio‐controlled by a stepwise cyanation via ortho‐lithiation/iodination from commercially available pentafluorosulfanyl arenes. The macrocyclization of the SF5‐containing phthalonitriles to SF5‐substituted Pcs required harsh conditions with the exception of the synthesis of β‐SF5‐substituted Pc. The regiospecificity of the newly developed SF5‐substituted Pcs observed by UV/Vis spectra and fluorescence quantum yields depend on the peripheral positon of the SF5 group. 相似文献

Silicon phthalocyanines and silicon naphthalocyanines, which are two derivatives in the family of hematoporphyrin, have been synthesized to assess their potential as photosensitizers for photodynamic therapy. For these complexes the red shift of their Q-band maximum absorption tends to depend on the nature of the axial substituent. The bimolecular rate coefficients for the interacting between photosensitizer, either SiNC or SiPC, and generated singlet molecular oxygen were determined from the time-resolved emission spectrum of singlet oxygen at 1.27 μm. On the basis of these data the electron-transfer quenching mechanism is discussed in relation to the Marcus model. 相似文献

Summary. A novel phthalodinitrile derivative carrying dimethylaminoethylsulfanyl groups at positions 4 and 5 was synthesized from
2-dimethylaminoethanethiol hydrochloride and 1,2-dichloro-4,5-dicyanobenzene. Its cyclotetramerization in the presence of
2-dimethylamino-ethanol or metal salts (CoCl2, Zn(OAc)2) gave metal-free or metal-containing phthalocyanines (M = Co or Zn). These phthalocyanines were converted into water soluble quaternized products by reaction with methyl iodide.
The new compounds were characterized by elemental analysis, IR, NMR, and electronic spectra. 相似文献
