Procedures have been developed for the synthesis of a series of metal complexes derived from water-soluble anionic and cationic octa-4,5-carboxyphthalocyanine-taurine and choline conjugates.Translated from Zhurnal Obshchei Khimii, Vol. 74, No. 11, 2004, pp. 1907–1911.Original Russian Text Copyright © 2004 by Mikhalenko, Soloveva, Lukyanets.For communication XXXVII, see [1].This revised version was published online in April 2005 with a corrected cover date.  相似文献

Cobalt, zinc, hydroxoaluminum, and iron complexes of N,N′,N″,N?-tetrakis(β-diethylaminoethyl) phthalocyanine-2,3 : 9,10 : 16,17 : 23,24-tetrakis(dicarboxamide) were synthesized and were converted into the corresponding water-soluble quaternary salts by treatment with methyl iodide, methyl p-toluenesulfonate, diethyl and dimethyl sulfates, and trimethyl phosphate. The electronic absorption spectra of the quaternary salts indicated their considerable aggregation in aqueous solution; the degree of aggregation decreases in going to solutions in ethanol and disappears in DMSO.  相似文献

Isotherms of adsorption of CO2 on a Ta2O5 surface and the same surface coated with a 0.5 monolayer of PdCl2 were measured over temperature and pressure ranges of 293–473 K and 0.015–1.5 Pa, respectively. It was established that, in the presence of PdCl2, the adsorption becomes greater in value and reversible. The isotherms were S-shaped, which was explained by the association of adsorbed CO2 molecules due to the change in their polarization caused by rising CO2 pressure. The influence of the temperature and PdCl2 on the adsorbate-adsorbate and adsorbate-adsorbent interaction constants were analyzed using the Kiselev isotherm and an isotherm that takes into account the interaction between the electrons of the semiconductor oxide and adsorbate molecules.  相似文献

A comparative study of oxidation of phenol, 3-chlorophenol, 4-chlorophenol, and 2,4-dichlorophenol on Pt/Ti and Ce,Pt/Ti electrocatalysts is performed via cyclic voltammetry. It is shown that the surface morphology and roughness of the anode do not change after modification with cerium. The formal kinetic orders of electrooxidation of all compounds are found to be less than one. It is shown that the β temperature coefficients of the rate of oxidation of chlorophenols grow by 10 to 50% when the Ce,Pt/Ti anode is used at a substrate concentration of 1 mM. A tenfold increase in concentration reduces the effect of cerium additive, except for 3-chlorophenol: the latter exhibits a 250% increase in the β value, compared to the Pt/Ti anode.  相似文献

A series of conjugates of sulfo- and carboxy-substituted phthalocyanines with rhodamines were prepared, and their electronic absorption and luminescence spectra were studied. An intramolecular transfer of the excitation energy from the rhodamine moiety (donor) to the phthalocyanine moiety (acceptor) was revealed.  相似文献
