Abstract:

In this work, the effect of fluorine and chlorine substituents in tetrasubstituted zinc phthalocyanines, introduced into the non-peripheral (ZnPcR4-np, R = F, Cl) and peripheral (ZnPcR4-p, R = F, Cl) positions of macrocycle, on their structure and chemiresistive sensor response to low concentration of ammonia is studied. The structure and morphology of the zinc phthalocyanines films (ZnPcR4) were investigated by X-ray diffraction and atomic force microscopy methods.

Abstract:

Topical photodynamic therapy (PDT) involves both local administration of a photosensitizing drug followed by illumination or irradiation of visible light, resulting in light-drug combinations to kill cells and microorganisms. PDT using tetra-sulfonate phthalocyanine, a second generation of hydrophilic photosensitizers, has recently become a good treatment option for treatment of skin malignances. However, tetra-sulfonate phthalocyanine must be delivered into the target layers of the skin to achieve promising results. Thus, strategies to improve the phthalocyanine cell uptake based on lipid-bas

Abstract:

Photodynamic therapy is a clinically approved alternative method for cancer treatment in which a combination of nontoxic drugs known as photosensitizers and oxygen is used.

Abstract:

The demand for fresh water is increasing daily, requiring industries to take action to reduce the need for fresh water. Winemaking industries represent a massive hydric impact by combining the water consumed and the high volume of wastewater produced. The sun-driven photooxidation process has been widely employed in removing wastewater pollutants. This work employed four photosensitizers, Rose Bengal, AlPcS4, ZnPcS4, and TPP, for water reuse in cellars. A secondary effluent has been investigated as a water matrix. Of all the photosensitizers (PS) employed, ZnPcS4 showed better chemical oxygen

Abstract:

Novel Zn (II) phthalocyanine and naphthalocyanine DBU complexes have been prepared in a one-pot synthesis reacting phthalonitrile precursors with an excess of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene). For the first time, it has been well evidenced that DBU played the role of coordinating axial ligand together with the well known role of strong base. Also, DBU complexes showed better solubility in organic solvents due to the coordination of the bulky axial DBU ligand, compared to the Zn (II) phthalocyanines and naphthalocyanines without coordinated DBU. The coordinating properties of DBU toward

Abstract:

Recently, significant progresses have been achieved in the fabrication of highly efficient perovskite solar cells, while major challenges, such as commercial viablity of exotic materials and their instability, remain as an obstacle. Hole transporting materials (HTMs) represent a tricky choice for the fabrication of efficient solar cells and the cost uneffective Spiro-OMeTAD continue to be so far the most obvious candidate. Semiconductors molecules, such as metallophthalocyanines (MPcs)1 appeared as a promising class of p-type material, since they are less expensive and more stable. In this com

Abstract:

Amino group modified phthalocyanines (Pcs) and their derivatives have attracted great attention in the field of photodynamic therapy (PDT) because of their satisfied anticancer activity. The existence of N atoms in these Pcs is very important because they not only provide water solubility of Pcs, but also greatly affect their PDT activity. To clear the influence of N atoms number on PDT activity of amino group modified Pcs and their derivatives, in this manuscript, two series of amine modified Pcs with different N atom number and their water soluble derivatives, hydrochloride and quaternizing

These novel compounds have been characterized by UV-vis spectroscopy in ethanol and ethanol:water (50:50) solutions. The electronic spectra of the mononuclear derivatives retain the main spectral features of ZnPc with a strong Q-band absorbance at 678 nm in ethanol and a less intense B-band at 370 nm.

Abstract:

The presence of a liquid electrolyte in dye-sensitized solar cells (DSSCs) is known to limit the time stability of these devices due to leakage and evaporation phenomena. To overcome this issue, gel-state electrolytes may represent a good solution in order to maintain stability and good performances, albeit at lower costs. In the present work, two different kinds of gel-electrolytes, based on poly (methyl methacrylate) (PMMA) and nanoclay agents, were investigated in DSSC-devices sensitized using β-substituted Zn-porphyrins (namely ZnPC4 and ZnPC12) with enveloping alkoxy chains of different l

Abstract The photodynamic impact of water-soluble zwitterionic zinc phthalocyanines (ZnPc1–4) was studied on pathogenic bacterial strains after specific light exposure (LED 665 nm). The structural differences between the studied ZnPc1–4 are in the positions and the numbers of substitution groups as well as in the bridging atoms (sulfur or oxygen) between substituents and macrocycle. The three peripherally substituted compounds (ZnPc1–3) are tetra-2-(N-propanesulfonic acid)oxypyridine (ZnPc1), tetra-2-(N-propanesulfonic acid)mercaptopyridine (ZnPc2), and octa-substituted 2-(N-propanesulfonic ac

The stabilization of G-Quadruplex DNA structures by ligands is a promising strategy for telomerase inhibition in cancer therapy since this enzyme is responsible for the unlimited proliferation of cancer cells. To assess the potential of a compound as a telomerase inhibitor, selectivity for quadruplex over duplex DNA is a fundamental attribute, as the drug must be able to recognize quadruplex DNA in the presence of a large amount of duplex DNA, in the cellular nucleus. By using different spectroscopic techniques, such as ultraviolet-visible, fluorescence and circular dichroism, this work evalua

Abstract:

Dopant-free metal phthalocyanines are viable alternatives to the classical Spiro-OMeTAD in perovskite solar cells (PSCs), due to their appealing optoelectrical properties and chemical stability. However, low carrier concentration, transportability, and narrow bandgap limit their application. Here, we designed and investigated six innovative asymmetrically substituted metal phthalocyanines (MPcs, M = Zn or Cu), and established the correlation between electronic structure, charge carrier transfer parameter, and core metal/substitutions in MPcs by transient absorbance spectroscopy and electronic
