AbstractThe inhibition effects of two phthalocyanine sulfonates on aluminum alloy 7075 were investigated in this study. The gravimetric test showed that the two compounds effectively inhibited the exfoliation corrosion of aluminum alloy 7075 in 1?mol/L hydrochloric acid. The electrochemical test showed the phthalocyanine sulfonates mainly acted as mixed-type inhibitors. The molecular dynamic simulation indicated that the phthalocyanine inhibitors selectively adsorbed on aluminum atoms, which inhibited the dealloying of aluminum from the alloy surface. In XPS analysis, the chemical adsorption between aluminum and phthalocyanine inhibitors was proven by the changes in the electronic binding energy of Al and N. 相似文献

文章测试了5种磺化金属酞菁在7种不同极性溶剂中的吸收光谱,用N icol理论研究了金属酞菁染料的溶剂效应。实验和理论结果表明,此类化合物最大吸收峰的波数与函数f(n,ε)存在良好的线性关系,线性相关系数都在0.93以上;而Bayliss函数项(n2-1)/(2n2+1)决定了最大吸收波长(λm ax)的位移变化,λm ax总体上随着溶剂折射率的增大而蓝移,随着溶剂极性的增强而红移。基于此结果,提出了通过选择合适的溶剂调节酞菁染料吸收峰的有效方法,从而使酞菁染料更好地应用于激光防护。 相似文献

The photophysical behaviour of chlorogallium 2,(3)-tetra-(2 pyridiloxy) phthalocyanine (ClGaT-2-PyPc) and its quaternised derivative were compared with that of the water soluble anionic tetrasulfonated gallium phthalocyanine ((OH)GaTSPc) and hydoxy gallium octacarboxy phthalocyanine ((OH)GaOCPc). Although both the quaternised compound and the tetrasulfonated gallium phthalocyanine aggregated in aq. solution at pH 11, resulting in low fluorescence and triplet yields, the presence of the surfactant Cremophore EL improved yields. Triplet quantum yields ranged from 0.52 to 0.70 and fluorescence quantum yields ranged from <0.01 to 0.21. The nature of substituent (sulfonate, carboxy and pyridiloxy) did not influence photophysical properties. Chlorogallium 2,(3)-tetra-(2 pyridiloxy) phthalocyanine and its quaternised derivative displayed longer triplet lifetime than both the tetrasulfonated gallium phthalocyanine ((OH)GaTSPc) and hydroxy gallium octacarboxy phthalocyanine in DMSO and in aq. media in both the presence and absence of surfactant. 相似文献

Fabrication of deodorizing fabric was tried by grafting metal phthalocyanine derivative, a catalytic deodorant, onto polypropylene (PP) nonwoven fabric. Fe(III)-4,4′,4″,4‴-tetra carboxamide phthalocyanine (Fe-TCMP) was synthesized. The Fe-TCMP showed high-deodorizing performance when tested for the elimination of 2-mercaptoethanol, an index material for bad-smelling compounds. The Fe-TCMP was converted to Fe(III)-4,4′,4″,4‴-tetracarboxylic acid phthalocyanine (Fe-TCAP) by hydrolysis to have carboxyl groups. It was chemically grafted on the surface of PP nonwoven fabric, which was surface modified to have amine groups with diaminocyclohexane (DACH) plasma. Such fabricated deodorizing fabric showed high-deodorizing performance for 2-mercaptoethanol. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 82: 839–846, 2001 相似文献

Metal free and some metal-perylene polymers as well as some metal phthalocyanine polymers were incorporated into butadiene styrene rubber (SBR) compounds as coloring agents. Ageing and UV resistance of the vulcanizates obtained were studied in terms of the mechanical properties. The dielectric properties of the vulcanizates were also discussed. The results obtained revealed that cobalt perylene and cobalt phthalocyanine polymers showed superior performance in SBR vulcanizates against thermal ageing and UV radiation. The optimum concentration of cobalt phthalocyanine polymer was found to be 1 phr (parts per hundred parts of rubber). 相似文献
