摘要

In this dissertation ,we study the synthesis and character of new substituted Phthalocyanine .Due to the widely appli‐cation of Pcs in the fields ,such as the communication ,medical treatment ,chemical industry and so on ,therefore ,they have been a hot topic over several decades by scientists .Nowadays ,scientists have prepared thousands of Pcs and their derivatives . However ,along with the human society development and the progress in science and technology ,the new phthalocyanine with novle characteristics are still the goal of the scientists .In this dissertion ,the synthetic methods of the phthlocyanine is im‐proved .The synthesis and characterization of 1 ,11 ,15 ,25‐tetrahydroxy‐4 ,8 ,18 ,22‐di(bridged dipropionate carboxyl) phthalocy‐anines are reported in this paper .The mixtures of malonic acid and 3 ,6‐dihydroxy‐phthalonitrile was added to water under stiri‐ing .Then ,a catalyst amount of sulfuric acid was added .The first synthetic precursor ,i .e .,malonic acid 3 ,3′‐bis(6‐hydroxy phthalonitrile) butter ,its molecular formula is C19 H8 N4 O6 .phthalocyanines was prepared by malonic acid 3 ,3′‐bis(6‐hydroxy phthalonitrile) butter and dihydrate zinc acetate ,copper acetate monohydrate in n‐amyl alcohol ,using DBU as a catalyst under the 135 ℃ ,molecular formula of phthalocyanine complexes is C38 H16 N8 O12 M .The product was characterized by Ultraviolet‐vis‐ible (UV/Vis) Spectrum absorption and fluorescence ,The results are agreement with the proposed structures .And electro‐chemical properties were studied .%对新型取代基酞菁和酞菁晶体合成和性质进行了研究。因为酞菁在信息、医疗、化工等众多领域有很广泛的应用，所以近百年来一直是科学家研究的热点课题。酞菁经过近百年的研究，科学家已经合成了上万种酞菁衍生物，但是，随着科技的不断进步，人类社会不断发展的需求，具有新特性的新型酞菁的获得仍是相关科技工作者孜孜以求的目标。为此，在本论文中，我们改进了合成方法，合成了新型的桥联酞菁材料：1，11，15，25‐四羟基‐4，8，18，22‐二（桥联二丙羧基）酞菁铜，表征其结构。并研究电化学性质。首先以丙二酸和3，6‐二羟基邻苯二腈为起始原料，以水为溶剂，加入浓硫酸作为催化剂，先合成前体，即丙二酸3，3′‐二（6–羟基邻苯二腈）脂。然后再用丙二酸3，3′‐二（6‐羟基邻苯二腈）脂与一水合乙酸铜，以正戊醇为溶剂，以DBU为催化剂，合成了1，11，15，25‐四羟基‐4，8，18，22‐二（桥联二丙羧基）酞菁铜，其分子式是C38 H16 N8 O12 Cu。对1，11，15，25‐四羟基‐4，8，18，22–二（桥联二丙羧基）酞菁铜进行紫外吸收及荧光光谱测定，证明合成产物是目标产物，并研究了1，11，15，25‐四羟基‐4，8，18，22‐二（桥联二丙羧基）酞菁铜的电化学性质。
