Synthesis And Electrochemical Catalysis Study Of Tetrasubstituted Metallophthalocyanine Derivatives

Due to the widely application of phthalocyanine in the areas, such as thesemiconductor devices, nonlinear optical materials, dye battery, liquid crystal displaymaterials, selective data storage devices and so on, therefore, they have been a hottopic over several decades by scientists. Nowadays, scientists have prepared tenthousands of phthalocyanine and their derivatives. However, along with the humansociety development and the progress in science and technology, the newphthalocyanine with novel characteristics and functions are still the goals of thescientists. In this dissertation, some new tetrasubstituted metallophthalocyaninederivatives are synthesized and their electrochemical catalytic activities forelectrochemical oxidation of nitrite are researched, and they have good watersolubility and excellent electrochemical activity.The main points of this dissertation are summarized as follows:1.In this dissertation, tetracarboxyl phthalocyanine iron(Ⅲ) and tetracarboxylphthalocyanine zinc are synthesized. The produces are characterized by FT-IR,Ultraviolet-visible spectra. And we study the solubility of tetracarboxylphthalocyanine iron(Ⅲ) in1-vinylimidazole and1-methylimidazole, and theenhancement of the solubility is due to the axial coordination reaction oftetracarboxyl phthalocyanine iron(Ⅲ) with1-vinylimidazole and1-methylimidazole. We also study the synthesis of phthalocyanine zinctetracarboxylic acid salt through the reaction of tetracarboxyl phthalocyaninezinc with hydrogen oxidation1-butyl-3-methylimidazolium (BMImOH). And thephthalocyanine zinc tetracarboxylic acid salt has good water solubility andexcellent electrochemical activity. The phthalocyanine zinc tetracarboxylic acidsalt modified glassy carbon electrode is prepared, and the electrochemicalcatalytic activity for electrochemical oxidation of nitrite on the modified glassycarbon electrode is researched, and the good result has been obtained.2.In this dissertation, tetranitro phthalocyanine zinc is synthesized, and it ischaracterized by FT-IR, Ultraviolet-visible spectra. Then, tetraamino phthalocyanine zinc is prepared through the reduction of tetranitro phthalocyanine zinc. Andtetra(2-chloro-1,3,5-triazinyl)aminophthalocyanine is synthesized through thesubstitution reaction of2-chloro-1,3,5-triazine with tetraamino phthalocyanine zinc,and the produce is characterized by FT-IR, Ultraviolet-visible spectra. Thetetra(2-chloro-1,3,5-triazinyl)aminophthalocyanine modified glassy carbonelectrode is prepared, and the electrochemical catalytic activity forelectrochemical oxidation of nitrite on the modified glassy carbon electrode isresearched, and the modified glassy carbon electrode has favorableelectrochemical catalytic activity.In conclusion, two novel water-soluble tetrasubstituted metallophthalocyaninederivatives are synthesized, and we study their electrochemical catalytic activityfor electrochemical oxidation of nitrite. And the good result has been obtained,so the excellent electrochemical catalysic activity of novel water-solubletetrasubstituted metallophthalocyanine derivatives have been proved.
