Synthesis and some physicochemical properties of the aqua complexes of covalent conjugates of platinum(II) with octacarboxy-substituted cobalt phthalocyanine

Efficient Oxygen Reduction Reaction Using Ruthenium Tetrakis(diaquaplatinum)Octacarboxyphthalocyanine Catalyst Supported on MWCNT Platform

“…All Other reagents were of analytical grade and were used as received from the suppliers without further purification. The ruthenium(II) tetrakis(diaquaplatinum)octacarboxyphthalocyanine (RuOCPcPt) was synthesised by adopting a similar strategy used for the cobalt derivative [24]. Basal plane pyrolytic graphite electrode (BPPGE, 5 mm diameter) was cleaned by gentle polishing on a p1200C Norton carborundum paper (Saint-Goban Abrasives, Isando, South Africa) followed by cleaning with cellotape process of removing graphite layers and finally rinsing in acetone to remove any adhesives.…”

Iron(ii) tetrakis(diaquaplatinum)octacarboxyphthalocyanine supported on multi-walled carbon nanotube platform: an efficient functional material for enhancing electron transfer kinetics and electrocatalytic oxidation of formic acid

“…All other reagents were of analytical grade and were used as received from the suppliers without further purification. Step 1: the iron(II) tetrakis(diaquaplatinum)octacarboxyphthalocyanine (PtFeOCPc) (III) was synthesised by adopting the same strategy reported for the cobalt derivative by Dolotova and Kaliya, 48 (Scheme 1). Briefly, the sodium salt of iron(II) octacarboxyphthalocyanine (II) (0.10 g) was dissolved in distilled water (12 mL) and methanol (106 mL), potassium tetrachloroplatinate (0.12 g, 0.28 mmol) dissolved in 50% ethanol (190 mL) was added to the solution of II and stirred for 3 h at room temperature.…”

“…The PtFeOCPc (Scheme 1, complex III) was synthesised following the same strategy used for the cobalt derivative. 48 As will be seen from the characterisation and electrocatalytic properties of the complex III, the introduction of the Pt at the periphery of the FeOCPc (complex I) led to changes in the physico-chemical properties of the complex I. For example, as also observed for the cobalt derivative by Dolotova and Kaliya, 48 the replacement of the ionic bond, Na + -O À (complex II), by the Pt-O covalent bond rendered the tetraplatinated iron phthalocyanine product III insoluble in water.…”

Copper and Nickel Complexes of tert-Butyl Substituted Phthalocyanines as Modifiers for Films Based on Polyvinyl Chloride and Adsorbents for Gas Chromatography

“…[1][2][3][4][5][6][7] Неослабевающий интерес к фталоцианинам обуслов-лен наличием у них ряда интересных с научной точки зрения и важных в плане практического использования характеристик, в число которых, к примеру, входят ценные красящие свойства металлокомплексов фталоци-анина и его многочисленных производных. [8] Комплексы фталоцианина с Cu, Ni, Co, Zn, Al и др., их галогенпро-изводные и сульфокислоты обладают весьма высокой для органических соединений термостойкостью, свето-прочностью, инертностью к щелочам, кислотам, малой растворимостью в большинстве растворителей, высокой укрывистостью, чистотой и интенсивностью окраски, [2] в связи с чем они могут быть полезны в такой важной области знаний, как бионика, [9] а также как высококаче-ственные пигменты. [10] В последнее время возможности использования цен-ных свойств фталоцианинов существенно расширились благодаря открытию и изучению их полупроводниковых свойств, [11] синтезу полимерных фталоцианинов.…”
