Karaoglan, Gulnur Keser research published ã€?Synthesis of a novel zinc phthalocyanine with peripherally coordinated Ru(II) complexes; sono-photochemical, photochemical and photophysical studiesã€? the research content is summarized as follows. Sono-photodynamic therapy (SPDT), which was used in the treatment of cancer cells and is advantageous in therapeutic results, was studied rarely academically as it is a new method. That’s why a novel multicomponent system, ZnPc-[Ru(bpy)₂(phen)]₄, as a photosensitizer (Ps) was synthesized by the condensation reaction of the sym. Zn phthalocyanine substituted with four 4-(4-formylphenoxy) groups at peripheral positions and Ru (II) bis(bipyridine)-phenanthroline complexes including amine group. The compounds were characterized by elemental anal., FTIR, ¹H NMR, UV-visible and MALDI-TOF MS spectral data and analyzed for photophysicochem. properties. Singlet O quantum yields of the photosensitizer were calculated using photochem. and sono-photochem. methods. When singlet O yields were compared, higher efficiencies were achieved in singlet O production by the sono-photochem. method (Φ_Δ= 0.72 in DMSO, 0.66 in DMF) compared to the photochem. method (Φ_Δ = 0.45 in DMSO, 0.43 in DMF). This work will give new sensitizers with high potential for use in SPDT.

Keshavananda Prabhu, C. P.;Aralekallu, Shambhulinga;Palanna, Manjunatha;Sajjan, Veeresh;Renuka, B.;Sannegowda, Lokesh Koodlur research published ã€?Novel polymeric zinc phthalocyanine for electro-oxidation and detection of ammoniaã€? the research content is summarized as follows. The design and development of new catalysts with low cost, high selectivity, and sensitivity for the electrochem. sensor applications is of huge interest. In this report, novel zinc tetra [4-[2-(1H-benzimidazol-2-yl) phenoxy]] phthalocyanine (ZnTBImPc) is prepared in a pure state with 87% yield. The characterization of the ligands and complex is carried out by combination of techniques like elemental anal., UV-visible (UV-Vis), Fourier-transform IR spectroscopy (FTIR), mass spectral, thermogravimetric anal. (TGA), X-ray diffraction (XRD), and electrochem. techniques. FTIR is useful in monitoring the progress of the reaction. The benzimidazole moiety of ZnTBImPc undergoes electropolymerization and thin, uniform polymeric layer deposits on the glassy carbon surface. The polymeric film was characterized by impedance spectra and charge transfer studies. The fabricated polymeric film electrode is applied for voltammetric sensing of ammonia which showed linear characteristics in 0.1 to 1.0 μM concentration range. The LOD was 30 nM with sensitivity of 237.25 μA μM^-1 cm^-2. The efficiency and sensitivity of ammonia oxidation at the poly(ZnTBImPc) are compared with the composite hybrid electrode of poly(ZnTBImPc) and carbon nanoparticle (CNP). The amperometric sensing of ammonia showed linear behavior in 50 to 500 nM concentration range. The RDE experiment revealed that the number of electrons involved in the ammonia oxidation is nearly 3. The polymeric electrode was subjected to the interference studies to evaluate the selectivity of the fabricated electrode and found that the co-existing mols. do not show interference during the detection of ammonia.

Kim, Yoonbin;Kim, Daekyu;Lee, Jeongyeon;Lee, Lawrence Yoon Suk;Ng, Dennis K. P. research published ã€?Tuning the Electrochemical Properties of Polymeric Cobalt Phthalocyanines for Efficient Water Splittingã€? the research content is summarized as follows. Polymeric metal phthalocyanines have great potential as electrocatalysts, yet their incorporation on a current collector without losing the activity of metal centers remains a challenge. Herein, a new strategy for preparing a series of polymeric cobalt phthalocyanines containing S linkers (pCoPc-1) or SO₂ linkers (pCoPc-2) and their tunable electrochem. properties are reported. The pCoPcs coated on various substrates show favorable electrocatalytic activities toward oxygen and hydrogen evolution reactions (OER and HER). Particularly, the pCoPc-1 layer on Co₃O₄ nanosheet arrays exerts a cooperative effect enhancing both the OER and HER performances, and the subsequent phosphorization (P@pCoPc-1/Co₃O₄|CC) significantly boosts the HER performance with enhanced hydrophilicity and conductivity The high permeability and stability reinforcement of the pCoPc-1 layer allow the phosphorization of underlying Co₃O₄ to CoP without degradation, which remarkably enhances OER and HER performances as manifested by low overpotentials of 320 and 120 mV at 10 mA cm^-2, resp. When engaged as a bifunctional electrocatalyst for the overall water splitting, the P@pCoPc-1/Co₃O₄|CC requires a low cell voltage of 1.672 V at 10 mA cm^-2, showing long-term durability and mech. robustness. This study demonstrates the collaborative catalytic role of polymeric macrocyclic compounds that offers versatile tunability and stability for various electrocatalytic reactions.

Oligoimide containing propargyl and phthalonitrile groups in one mol. (OI-PR-PN) was synthesized by a facile and eco-friendly method in benzoic acid melt. To incorporate side propargyl groups into the polyimide backbone, a new monomer was developed – 5-(2-propyn-1-yloxy) benzene-1,3-diamine (PBD). The OI-PR-PN dual-curing behavior was studied by DSC and FT-IR methods. The curing of phthalonitrile groups can be promoted by the intermediates formed during the propargyl groups polymerization This allows crosslinking of phthalonitrile groups at 300-350°C in one component system. OI-PR-PN showed good solubility in low b.p. solvents and had low melt viscosity (up to 8 Pas at 250°C). The temperatures of 10% weight loss of the cross-linked OI-PR-PN and oligoimide containing only propargyl groups (OI-PR) are 496°C and 450°C correspondingly. The completely cured OI-PR-PN glass transition temperature measured by dynamic mech. anal. was 424°C with a storage modulus 4.2 GPa at 50°C. The possibility of crosslinking without using curing additives with a combination of excellent thermal and mech. properties indicates the potential of OI-PR-PN as a matrix for composite manufacturing

A cascade process for the straightforward one-pot conversion of β-ketonitriles into β-hydroxyamides was reported. The process, that proceeded in water employing the arene-ruthenium(II) complex [RuCl2(η6-p-cymene){P(4-C6H4F)2Cl}] as catalyst in combination with sodium formate involved the initial hydration of the β-ketonitrile substrates to generate the corresponding β-ketoamide intermediates which subsequently undergo the transfer hydrogenation (TH) of the carbonyl group. Employing a family of forty different β-ketonitriles featuring diverse substitution patterns, the scope and limitations of the processed was established.
