The Research On The Effects Of Asymmetric Nickel Phthalocyanine Yield With The Raw Material Ratio Change

At Present, all countries are faced with energy shortage, environmentaldegradation and other issues,so how to make full use of clean, pollution-free energyreplaced will be the focus that human beings have been trying to in the study.Accidentally discovered phthalocyanine since1907, has a history of more thanone hundred years. From the initial use as an organic pigment, it has been graduallyextended to various fields., such as in optical sensors, photovoltaic devices, cancertreatment, photocatalysis, photodynamic therapy and photosensitization batteries andsolar cells, and oher aspects all have important applications.Phthalocyanine especially asymmetric phthalocyanine has excellent performancein many areas. compared with the symmetric phthalocyanine, which has a strong nearinfrared absorption, excellent second order nonlinear optical properties and goodphotoconductivity, solubility and film-forming properties and so on. These featuresmake asymmetric phthalocyanine become the focus of research chemists. In theresearch of asymmetric phthalocyanine A3B is studied most.This thesis is on the basis of predecessors’ synthetic A3B phthalocyanine furtherto perfect them. Mainly on the following five kinds of asymmetric phthalocyanine2-(6-Ethly-4,5-dimethyl-4H-cyclopenta[b]furan)-9,16,23-tris(5-methyl-2-isopropyl phenoxy) nickel phthalocyanine,2-(6-Ethyl-4-methyl-4H-cyclopenta[b]furan)-9,16,23-tris(2-isopropyl phenoxy)nickel phthalocyanine,2-(6-Ethyl-5-methyl-4H-cyclopenta[b]furan)-9,16,23-tris(4-isopropyl phenoxy) nickel phthalocyanine,2-(6-isopropyl-4-methyl-4H-cyclopenta[b]furan)-9,16,23-tris (2-tert-butyl phenoxy) nickelphthalocyanine,2-(6-isopropyl-5-methyl-4H-cyclopenta[b]furan)-9,16,23-tris (4-tert-butyl phenoxy) nickel phthalocyanine respective yield varied with the change ofraw material ratio for research and summary. This will for asymmetric synthesis ofphthalocyanine and mechanism research has the vital significance.Conclusion:(1) As the portion of precursor compounds and metal increases, the yield ofasymmetric phthalocyanine showed a gradual increasing trend, and when the rawmaterials ratio is4:1, the asymmetric phthalocyanine reached to the maximum yields. (2) Based on the research of the five kinds of asymmetric phthalocyanine, foundthat when the more alkyl phenol on replacing, asymmetric phthalocyanine yield ishigher, and the reaction process is relatively easy; Asymmetric yield ofphthalocyanine has nothing to do with the position of the substituent.
