Research On Yield Change With The Temperature Of Three Asymmetric Nickel Phthalocyanines

Since the21st century, the global faced a lot of problems, such as environmentalpollution, lack of energy and so on. Although people have started to develop endless solarenergy to relieve the energy problem, but it still can’t satisyf people’s needs. The developmentof new energy and application of energy-saving material are goals of all people in the future.In1907, phthalocyanines was born accidentally and widely used. In these years, the useof phthalocyanines have from traditional dye to near infrared absorption, solar cells, cancertreatment, chemical sensor device and many other aspects. The research of phthalocyanineshas from accidental synthesis to directional synthesis, modiifcation. All kinds ofmulti-functional phthalocyanines have been occurred and combined other advanced materialcombination, such as Ceo.Asymmetric phthalocyanines relative to the symmetrical phthalocyanines have goodcharacteristics in many aspects, such as: good second-order nonlinear optical activity, goodsolubility, optical conductivity and iflm, etc. These unique characteristics make theasymmetric phthalocyanines has very good application prospects. The advantage of AB₃typein all kinds of asymmetric phthalocyanines is more outstanding.This paper aims to further research on AB₃type asymmetric phthalocyanines based ontheir study. Three structure-similar asymmetric phthalocyanines:2-（2-isopropylphenoxy）-9,16,23-three（5-methyl-2-isopropylphenoxy） nickel phthalocyanine,2-（4-isopropylphenoxy）-9,16,23-three（4-tert-butyl-phenoxy） nickel phthalocyanine,2-（2-isopropylphenoxy）-9,16,23-three（2-tert-butyl-phenoxy） nickel phthalocyanine, theiryield changes with the change of temperature and I get the summary. The research of yield ofthree asymmetric phthalocyanines has the important practical signiifcance and theoreticalbasis for asymmetric phthalocyaniness synthesis mechanism and application.Conclusion:（1）The yield of three asymmetric phthalocyanines increases with the rise of temperature,and in170°C or so, there was a surge in180°C or so to achieve maximum.（2）Through the three structure similar precursor synthesis asymmetric phthalocyanines,we found that the more the alkylation number of phenol ring, the greater the yield, and thelow temperature achieve maximum yield.
