Testing Optical Conductivity And Near-Infrared Absorption Of The Asymmetry Nickel-Phthalocyanine Film

Since the beginning of21st century, global energy occurred problems such as crisis environmental degradation, the infinity of the solar energy resource development and applications as a solution to the global energy and environmental issues by the basic methods in the various countries.Due to phthalocyanine molecular outside ring have different of electronic groups,that formed asymmetric phthalocyanine derivatives, compared to general of phthalocyanine, asymmetric with the good of the sencond step,the three step non-linear optical activehas and superior of dissolved, and easy formed film, in the future,as the physical, chemical, and optical performance to demonstrate their own potential application, andit has become today’s organic functional materials researched. Asymmetrical phthalocyanine’special performances, such as in the near-infrared absorption, A3B phthalocyanine is easy to film, push-pull type electronic substituent A3B phthalocyanine’conduction is better, therefore, on the application A3B-phthalocyanine had more advantages than symmetric phthalocyanine. However, because synthesis methods ofA3B-type asymmetric phthalocyanine is small, so this type of compounds less kind, which greatly limits its application. On the basis of this method in the synthesis of symmetric phthalocyanine, preparation of a new type of A3B nickel phthalocyanine, and its some natures tested, A3B type asymmetric nickel phthalocyanine’synthesis is currently in the early stages. As to the mechanism is unclear, the synthesis method has the following disadvantages:separation and purification difficult,the random and uncertain target molecules.At the same time, polymethylmethacrylate is good in density, high mechanical strength, resistance to stretching, resistance to shock, superior light transmittance, and so on characteristics, as well as in the medical, industrial, military, construction and conductive materials widely used in fields,the development space is very large, and broad market prospects. Combined with the organic film industry is young, it is also its own characteristics. The asymmetric nickel phthalocyanine is good in acid resistance, alkali resistance of organic solvent resistance, the asymmetric nickel phthalocyanine doped PMMA insufficiently improve organic film,which can be applied to every aspect of our lives, so that the light heat and power conversion material is ideal for our use of solar energy materials. In this article:(1)by DBU catalyst, in an instant high temperature (170℃) produced in the near-infrared absorption of substances B and C.And by UV-Vis-NIR (UV-visible near-infrared absorption spectrometry), FT-IR (infrared spectroscopy), MS (mass spectrometry), NMR (nuclear magnetic resonance) characterization. (2) Discuss substance B cyclic voltammetry of electro-chemical nature, yield and photoconductive properties, compared the solubility of substances B and C.(3) Preparation of asymmetric nickel phthalocyanine photothermal conversion coating of polymethyl methacrylate and polymethyl methacrylate film, respectively, their UV-visible near-infrared absorption are tested. I hope that as an organic smart materials in the translated material it is widely used.
