“…The HOMO-LUMO gap of compound 4 evaluated as the potential difference between the first oxidation and first reduction corresponds to the high value of 2.6 V, which is indicative of the high inter-molecular electron transfer abilities and potential of the developed compound as a sensing semiconductor material for both electron-donating and electron-withdrawing analytes [ 20 , 21 ]. Zn(II)Pc 4 gives a ring-based redox process only due to the electro-inactive nature of the Zn(II) metal coordinated to the macrocycle, as the energy level of the d orbital of the zinc is placed out of the HOMO-LUMO energy levels [ 22 ]. This result may also be due to the smaller atomic radius of Zn(II) metal compared to other metal atomic radii such as Co and Mn [ 17 ].…”

In this work, we have described the synthesis and characterization of novel zinc (II) phthalocyanine bearing four 2-(2,4-dichloro-benzyl)-4-(1,1,3,3-tetramethyl-butyl)-phenoxy substituents on the peripheral positions. The compound was characterized by elemental analysis and different spectroscopic techniques, such as FT-IR, 1H NMR, MALDI-TOF, and UV-Vis. The Zn (II) phthalocyanine shows excellent solubility in organic solvents such as dichloromethane (DCM), n-hexane, chloroform, tetrahydrofuran (THF), and toluene. Photochemical and electrochemical characterizations of the complex were performed by UV-Vis, fluorescence spectroscopy, and cyclic voltammetry. Its good solubility allows a direct deposition of this compound as film, which has been tested as a solid-state sensing material in gravimetric chemical sensors for gas detection, and the obtained results indicate its potential for qualitative discrimination and quantitative assessment of various volatile organic compounds, among them methanol, n-hexane, triethylamine (TEA), toluene and DCM, in a wide concentration range.

“…Phthalocyanine complexes (Pcs) are a class of aromatic compounds, which have analogues structure to that of porphyrins. Due to their thermal, chemical and light stability, [1,2] metal phthalocyanines (MPcs) have been widely used in many fields, including commercial pigments, [3,4] chemical sensors, [5][6][7][8] security devices, [9] information storage, [10] electrocatalytic reagents, [11][12][13][14] and photodynamic therapy. [15][16][17][18] In recent years, MPcs have attracted considerable attention in catalysis fields [19][20][21][22][23][24] due to the high catalytic activity of MPc can be related to the central metal ions.…”

Photocatalysis is a fast and economically attractive option for oxidation reactions. Herein, 4‐(5‐iodopyridin‐2‐yloxy)phthalocyaninato cobalt(II) (P‐CoPc) and 4‐(4‐methylquinolin‐2‐yloxy)phthalocyaninato cobalt(II) (Q‐CoPc) were synthesized and characterized with spectroscopic data (FT‐IR, UV‐Vis, and mass spectra). The parameters affecting the photocatalytic activity such as substrate amount, oxidant type, substitution group, and solvent effect were studied. Both catalysts show high benzaldehyde selectivity with high TON and TOF values (470 and 1880 for P‐CoPc and 375 and 1500 for Q‐CoPc, respectively). The best photoxidation conditions were determined that 1/1500/500 (cat/subs./ox. ratio) in DMSO and in the presence of light. Aggregation and photodegradation studies of P‐CoPc and Q‐CoPc have also carried out in this work.

“…Phthalocyanines (Pcs), which have planar macrocyclic molecules and contain nitrogen atoms in the inner loop, contain a class of highly robust and versatile chemical compounds [21]. Phthalocyanines, which are still of great technological importance for the production of green and blue pigments, have applications such as such as DNA-binding and enzyme inhibition [22], catalysts [23,24], metal sensors [25], electrochemistry [26,27], solar cells [28], Langmuir-Blodgett films [29], fluorometric properties [25], liquid crystals [30], photodynamic therapy (PDT) [31], electrophotography [32], antimicrobial agent [33], optical disks [34], electrochromic displays [35], antioxidant [36] and modified supports in recent years. The leismania activity studies of phthalocyanines, which have been studied in many application…”

In this study, in vitro leishmanicidal activity of different chalcone compounds (5-8), phthalonitrile derivatives (5a-8a), and zinc phthalocyanine (5b-8b) complexes bearing chalcone compound in peripheral positions were investigated. Phthalonitrile derivatives were obtained in the reaction of 4-nitrophthalonitrile with chalcone compound obtained by the reaction of acetophenone and various aldehydes. Zinc phthalocyanine complexes containing chalcone in the peripheral position were obtained as a result of the reaction of the synthesized phthalonitrile derivative with Zn(CH₃COO)₂ metal salt. The characterization of the synthesized original compounds (8, 8a and 8b) was performed by various spectroscopic methods (IR, 1H and 13C NMR, MALDI-TOF-MS and UV-Vis). Leishmaniasis is a disease lead to by parasites of the genus Leishmania, which can result in death as well as various clinical syndromes, generally in developing countries. New drug studies are needed because the drugs used in the treatment are toxic and resistance develops against them. In this study, the leishmaniacidal activities of synthesized chalcone, phthalonitrile and phthalocyanine series substances against Leishmania infantum and Leishmania major parasites were evaluated for the first time.
