“…The transducers used in this study contain 10 finger pairs of Cr/Au interdigitated electrodes. These IDTs were fabricated according to our reported procedures [30,58]. Certain concentrated solutions of compounds 3-5 were prepared in eppendorf tubes by dissolving the compounds in DMF (N,N-dimethylformamide, HCON(CH 3 ) 2 ) at room temperature.…”

“…Metallophthalocyanines (MPc) are organic p-type semiconductors and have been extensively used as a sensitive material in gas sensors such as acetone and chloroform [30], xylene [31], NO 2 [32], and toluene sensors [30,33]. Volatile Organic Compounds (VOCs) are found in nature as a result of industrial and home applications such as resins, dyes and cleaners [34].…”

ABSTRACT:The synthesis of metallophthalocyanines (M = Co, Cu, Mn) bearing four ethyl 7-oxy-4,8-dimethylcoumarin-3-propanoate moieties was performed. These novel compounds were characterized by elemental analysis, 1 H-NMR spectroscopy, FT-IR, UV-vis and mass spectral data. DC and AC electrical properties of the films of metallophthalocyanines were investigated in the temperature range of 295-523 K. AC measurements were performed in the frequency range of 40-10 5 Hz. Activation energy values of the films took place between 0.55 eV-0.93 eV. Impedance spectroscopy measurements revealed that bulk resistance decreases with increasing temperature, indicating semiconductor properties. DC conductivity results also supported this result. Their gas sensing properties were also investigated for the vapors of Volatile Organic Compounds (VOCs), n-butyl acetate (200-3200 ppm) and ammonia (7000-56000 ppm) between temperatures 25-100 °C. Sensitivity and response times of the films for the tested vapors were reported. The results were found to be reversible and sensitive to the vapors of n-butyl acetate and ammonia. It was found that Mn(OAc)Pc showed better sensitivity than CoPc and CuPc for n-butyl acetate vapors at all measured vapor concentrations and temperatures. Mn(OAc)Pc also showed better sensitivity than CoPc and CuPc for ammonia vapors at 22 °C.

“…Phthalocyanines (Pcs), which are an important family of the macrocyclic compounds class, have many uses, e.g., as gas sensors, catalysts, solar cells, electrochromic devices, Langmuir Blodgett films, liquid crystals, and photosensitizers, in photodynamic cancer therapy (PDT). Photodynamic cancer therapy from these areas of use is very important in their studies of elimination of the tumor tissues without the need for surgical intervention.…”

The synthesis, characterization, aggregation behavior, theoretical studies, and investigation of antimicrobial, antidiabetic, and anticholinergic properties of 4-(2-(5amino-4-(4-bromophenyl)-3-methyl-1H-pyrazol-1-yl)ethoxy)phthalonitrile (2) and its soluble aminopyrazole-substituted peripheral metallo (Mn, Co, and Ni)-phthalocyanine complexes (3-5) are reported for the first time. The synthesized compounds and phthalocyanine complexes were characterized spectroscopically. The new phthalonitrile derivative (2) and its peripheral metallophthalocyanine complexes (3-5) were found to be effective inhibitors of α-glycosidase, acetylcholinesterase (AChE), human carbonic anhydrase I and II isoforms (hCA I and II), and butyrylcholinesterase (BChE) with K i values in the range of 1.55 ± 0.47 to 10.85 ± 3.43 nM for α-glycosidase,8.44 ± 0.32 to 21.31 ± 7.91 nM for hCA I, 11.73 ± 2.82 to 31.03 ± 4.81 nM for hCA II, 101.62 ± 26.58 to 326.54 ± 89.67 nM for AChE, and 68.68 ± 11.15 to 109.53 ± 19.55 nM for BChE. This is the first study of peripherally substituted phthalocyanines containing an aminopyrazole group as potential carbonic anhydrase enzyme inhibitor. Also, the antimicrobial activities of the synthesized compounds were evaluated against six microorganisms (four bacteria and two Candida species) using the broth microdilution method. The gram-positive bacteria were detected to be more sensitive than gram-negative bacteria and yeasts in the synthesized compounds.

In this study, novel phthalonitrile derivatives (1 and 2) and their peripherally and non‐peripherally tetra (4‐isopropylbenzyl)oxy‐substituted zinc and chloroindium phthalocyanine complexes (3‐6) have been prepared for the first time. The synthesized phthalonitrile derivatives and phthalocyanine complexes were characterized spectroscopically. Not only the chloroindium phthalocyanines but also zinc phthalocyanines are essentially free from aggregation in THF at the studied micromolar concentration. The purpose is to compare the effects of two types of substitution on the phthalocyanines to be used as sensitizers in photodynamic therapy (PDT). Photophysical and photochemical properties of all phthalocyanines are investigated and the results showed that the peripheral phthalocyanines more effectively photooxidize DPBF through singlet oxygen. The photochemical results showed that both ZnPc (3 and 5) and InPc (4 and 6) can be used as sensitizers in PDT because of their very high singlet oxygen quantum yields (range from 0.80 to 0.97).
