Several conjugates of metallophthalocyanines with deoxyribooligonucleotides were synthesized to investigate sequence-specific modification of DNA by them. Oligonucleotide parts of these conjugates were responsible for the recognition of selected complementary sequences on the DNA target. Metallophthalocyanines were able to induce the DNA modification: phthalocyanines of Zn(II) and Al(III) were ...

Electron variability and complex formation of transition metal phthalocyanine are discussed. Under proper conditions the well-known metal(n) phthalocyanines [MPc] (M = Cr, Mn, Fe, Co, Ni, Cu, Zn) can take up four or, in two cases, five electrons. To elucidate the electronic structure of the isolated anionic complexes Li[MPc] m THF a simple LCAO—MO model was derived which proved well suited to t...

Using MP as the tracer, we found LDL centered in fraction 5, HDL at fractions 14-15 and albumin at 20-21. When DMF was used to solubilize ZnBPc, density gradient ultracentrifugation indicated localization of the agent to two fractions of buoyant density between HDL and LDL (Fig. 1(b) ). When either CRM or TW80 was used for formulation, more than 90% ofthe ZnBPc was found in the LDL fraction (Fi...

A non-aggregated Zn(ii)octa(2,6-diphenylphenoxy) phthalocyanine (coded as TT80) has been used as a hole-transporting material for perovskite solar cells. The cells were fabricated under three different configurations by changing the uptake solvent (chlorobenzene or toluene) and incorporating additives (bis(trifluoromethane) sulfonimide lithium salt (LiTFSI) and 4-tert-butylpyridine (TBP). A pow...

Considerable efforts have been made in recent years to identify an optimal treatment method for the removal of antibiotics from wastewaters. A series supramolecular organic-inorganic magnetic composites containing Zn-modified MgAl LDHs and Cu-phthalocyanine as photosensitizers were prepared with aim removing β-lactam aqueous solutions. The characterization these materials confirmed anchorage on...

Objective(s)   Although photodynamic therapy is considered as a noninvasive method, most photosensitizers are susceptible to  ultrasound.  Therefore,  it  is  expected  that  the  combination of  two  activation  methods  might  have  a synergistic effect. This probable effect has been investigated in this study.   Materials and Methods   This  study  was  conducted  on  colon  carcinoma ...

A novel straightforward methodology to organize discrete heterogeneous stacks of porphyrin and phthalocyanine employed an imidazolyl-to-zinc complementary coordination protocol for a Zn(II) phthalocyanine that contains an imidazolyl terminal with an ethynylporphyrin as a coplanar spacer. Structural elucidation was performed by means of size-exclusion chromatography, spectral titration, and NMR ...

In this study, the preparation of some novel metallophthalocyanine (MPcs) complexes substituted with octakis(mercaptopropylisobutyl-POSS) functional group was achieved. By the reaction of [1-(3-mercapto)propyl-3,5,7,9,11,13,15-isobutylpentacyclo[9.5.1.1(3,9).1(5,15).1(7,13)]octasiloxane 1 with 4,5-dichloro-1,2-dicyanobenzene 2 in THF as the solvent in the presence of K2CO3 as the base, the phth...

Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.

copper (ii) phthalocyanine and 2, 9, 16, 23 tetrakis nitro copper (ii) phthalocyanine has been synthesized respectively from phthalonitrile and 4-nitro phthalonitrile under solvent-free condition using two different catalysts over nanodimensional zeolites. 4-nitro phthalonitrile synthesized from phthaimide in three steps. the newly prepared compounds have been characterized by ir, uv-vis,1h nm...
