“…This electronic structure adds interesting properties to the compound by providing delocalization [2]. In this context, solar cells [3,4], non-linear optics [5], chemical sensors [6], liquid crystals [7], laser dyes [8], photocatalytic [9], catalytic [10], photovoltaic [11], photochromic [12] and photodynamic therapy(PDT) [13,14] are being investigated extensively for obtaining photosensitive agents. Despite these wide uses, there are problems with phthalocyanines that need to be investigated.…”

The 4-(2-(3,4-dimethoxyphenoxy) phenoxy) phthalonitrile was synthesized as the starting material of new syntheses. Zinc, copper, and cobalt phthalocyanines were achieved by reaction of starting compound with Zn(CH3COO)2, CuCl2 and CoCl2 metal salts. Basic spectroscopic methods such as nuclear magnetic resonance electronic 2 absorption, mass and infrared were used in the structure characterization of the compounds. Absorption, excitation and emission measurements of fluorescence zinc phthalocyanine compound were also investigated in THF. Then, structural, energy and electronic properties for synthesized metallophthalocyanines were determined by quantum chemical calculations including DFT method. The band gap of HOMO and LUMO was determined to be chemically active. Global reactivity (I, A, η, s, μ, χ, ω) and non-linear properties were studied. In addition, molecular electrostatic potential (MEP) maps were drawn to identify potential reactive regions of metallo phthalocyanine (M-Pc) compounds. Photovoltaic performances of phthalocyanine compounds for dye sensitive solar cells were investigated. Solar conversion efficiency of DSSC based on copper, zinc and cobalt phthalocyanine compounds was 1.69%, 1.35% and 1.54%, respectively. Compounds have good solubility and show nonlinear optical properties. Zinc phthalocyanine gave fluorescence emission.

“…Phthalocyanines (Pcs) are stable molecules against heat, light and solvents. Due to the these properties, they have been used for many years in different fields such as electrical conductivity, optical storage devices, [ 1 ] gas sensors, antioxidant potential, dyes, and pigments, [ 2,3 ] photovoltaic optics, [ 4–6 ] solar cells, [ 7–9 ] laser dyes, [ 10,11 ] chemical sensors, [ 12–15 ] nonlinear optics, [ 16,17 ] semiconductors, [ 18–20 ] liquid crystals, [ 21 ] catalytic activity, electrochromic properties, and paint industries. [ 22,23 ] Also, phthalocyanines are used as an alternative treatment and diagnostic technique for cancer, and are used as photosensitizers in PDT by stimulating electrons from molecular oxygen transferred to reactive single oxygen species (ROS) in tissue.…”

In this study, two novel metallophthalocyanines (ZnPc and CoPc) were synthesized using the corresponding metal salts 4‐(4‐(4‐[4‐chlorophenyl]‐5‐methylisoxazol‐3‐yl)phenoxy)‐phthalonitrile (11), prepared from the reaction of 4‐nitrophthalonitrile and 4‐(4‐[4‐chlorophenyl]‐5‐methylisoxazol‐3‐yl)phenol (9). These metallophthalocyanines (MPcs) showed quite solubility in organic solvents such as dichloromethane (DCM), tetrahydrofuran (THF), dimethyl formamide (DMF), and dimethylsulfoxide (DMSO). The novel compounds 11a and 11b have been characterized using their UV–Vis, FT–IR, 1H NMR, 13C NMR, X‐Ray, and MALDI–TOF mass spectra. Supporting information cocerning with the study has been supplied. Photochemical, photophysical, and cyclic voltagram properties of these novel 4‐(4‐(4‐[4‐chlorophenyl]‐5‐methylisoxazol‐3‐yl)phenoxy substituted metallophthalocyanines (11a and 11b) were determined in DMF. DNA binding, metal chelating effect assay, and DPPH [2,2‐diphenyl‐1‐picrylhydrazyl hydrate] radical scavenging assay and electrochemical studies of MPcs were investigated. Further, the inhibitory effects of the COX‐inhibitor based novel metallophthalocyanines (11a and 11b) and their ligands (10 and 11) were examined on human erythrocyte carbonic anhydrase I (hCA‐I) and II (hCA‐II) isoenzymes, and the synthesized molecules exhibited very strong inhibitory effects on both isoforms. In addition, the hCA‐I and hCA‐II inhibition potential of Zn (II) and Co (II) Phthalocyanine complexes was supported by molecular docking studies. The binding interaction of metallophthalocyanines complexes 11a, 11b enzymes were analyzed in detail.

In this study, the synthesis and characterization of new substituted metallophthalocyanines are described. A new phthalonitrile, 4‐(5‐tert‐butyl‐2‐hydroxyphenoxy)‐5‐chlorophthalonitrile (3) was prepared. New compounds were characterized by UV–Vis, IR, 1H NMR, and elemental analysis. The aggregation behavior of the cobalt (II), magnesium (II) and copper (II) phthalocyanines were studied in tetrahydrofuran and in known concentration ranges. The antioxidant activities of compounds were evaluated. Their radical‐scavenging capacity, metal chelating activity and reducing power was fully studied. The compound 3 showed 100% chelating activity as EDTA at concentration 50 mg/L. The DNA interaction of copper (II) phthalocyanine compound (6) was studied using UV/Vis titration, gel electrophoresis, cyclic voltammetry. The results indicated that compound 6 interacts with CT‐DNA via intercalation binding mode.
