Çelenk Kaya, Elif; Ersoy, Sibel; Durmuş, Mahmut; Kantekin, Halit
4-(3-(Trifluoromethyl)benzylthio)phthalonitrile (1) was synthesized. Metal-free phthalocyanine 2, zinc(II) phthalocyanine 3 and cobalt(II) phthalocyanine 4 were synthesized starting with dinitrile compound 1. Photodynamic therapy properties of 2 and 3 were studied.

Kaya, Elif Çelenk; Kantekin, Halit; Kaya, Afşin Ahmet; Dakoǧlu, Asuman; Öksüz, Sümeyra; Şişik, Hanife
Tetrasubstituted zinc, cobalt, nickel, copper and lead phthalocyanines bearing four 12-membered diazadithia macrocyclic moieties on peripheral positions have been synthesised by cyclotetramerisation reaction of 1,10-ditosyl-1,2,3,5,6,8,9,10-octahydrobenzo[h][1,4,7,10] dithiadiazacyclododecine-12,13-dicarbonitrile and corresponding anhydrous metal salts under microwave irradiation. The thermal stabilities of the phthalocyanine compounds have determined by thermogravimetric analysis.

Nas, Asiye; Kaya, Elif Celenk; Kantekin, Halit; Sökmen, Atalay; Çakir, Volkan
This work reports on a new symmetrically substituted metal-free phthalocyanine and its transition metal complexes which were prepared by a condensation of N,N'-[propan-1,3-diilbis(tiyoetan-2,1-diil)]bis(4-methylbenzenesulfonamid) (1) and 1,2-bis(2-iodomercaptoethyl)-4,5-dicyanobenzene (2) with NiCl(2), ZnCl(2), CoCl(2), CuCl(2), and PbO salts in 2-(dimethylamino) ethanol, respectively. The phthalocyanines bearing thia and aza donor atoms at the peripheral position were characterized by IR, UV-Vis, (1)H NMR, (13)C NMR, Mass spectra, and elemental analysis data. The thermal behaviors of 4-9 were investigated by TG/DTA. Novel phthalocyanines were also investigated for enlightening their possible biological activities by employing antimicrobial (antibacterial and antifungal), antineoplastic and antioxidative assays. Of all tested, four samples exhibited antimicrobial activity against test microorganisms, among which, Branhamella catarrhalis was the most sensitive one with a MIC value around 0.312 mg/mL followed by a yeast, Candida albicans (MIC. 0.625 mg/mL). Due to their colored nature, the samples were found not to be applicable for antioxidative and antineoplastic assays. (C) 2011 Elsevier B. V. All rights reserved.

Kaya, Elif Celenk; Karadeniz, Huelya; Kantekin, Halit
A tetranitrile monomer was synthesized by nucleophilic aromatic substitution of N,N'-(2,2'-(propane-1,3-diylbis(sulfanediyl))bis(ethane-2,1-diyl))bis(4-methylbenzenesulfonamide) onto 4-nitrophthalonitrile. A metal-free phthalocyanine polymer was prepared by the reaction of the tetranitrile monomer under N-2 in the presence of 2-(dimethylamino)ethanol at 145 degrees C for 24 h. Zinc(II), copper(II), cobalt(II), nickel(II), lead (II), phthalocyanine polymers were prepared by reaction of the tetranitrile with the chlorides of zinc (II), copper (II), cobalt (II), nickel (II), lead (II), employing microwave irradiation in the presence 2-(dimethylamino)ethanol at 175 degrees C, 350 W for 10 min. The thermal stabilities of the phthalocyanine compounds were determined by thermogravimetric analysis. The new compounds were characterized by a combination of IR, H-1 NMR, C-13 NMR, UV-vis, elemental analysis and MS spectral data. (C) 2009 Elsevier Ltd. All rights reserved.
