Abstract

This is a method for preparing the isomorphic heteronuclear cubane metal cluster molecule functionality material. Lead sulfureted hydrogen into hartshorn of tungstenic acid or Sodium Molybdate and get 3-thio-ammonium tungstate and 3-thio-molybdate that is collected on a membrane filter by filtration under suction and desiccation. Add 3-thio-ammonium tungstate and 3-thio-molybdate into organic solvent, mix to entirely dissolve and get the 3-thio-ammonium tungstate and 3-thio-molybdate solution. Add cuprous halide into the mixture solvent of dimethylpyridine and volatile organic compounds solvent, mix to whole dissolution to get the cuprous halide solution. Drop 3-thio-ammonium tungstate or 3-thio-molybdate solution into cuprous halide solution with standing whisk.The reaction solution undergoes the heating, refluence, volatilization, crystal and desiccation to get the isomorphic heteronuclear cubane thio-metal cluster molecule function material. It can get the isomorphic heteronuclear cubane thio-metal cluster molecule functionality material that has signal conversion function of non-linearity refraction.

Description

a technical field [0001] The invention relates to the preparation of nonlinear optical materials, in particular to a method for preparing isomorphic heteronuclear cubane type thiometal cluster molecular functional materials with nonlinear refraction signal conversion function. Two background technology [0002] Nonlinear optical functional materials are currently a hot spot in the research and application of optoelectronic information functional materials at home and abroad. These optical functional materials can not only be applied to the protection of photosensitive devices and human eyes from the damage of high-intensity lasers, but also can be developed and applied to photonic communication, transmission and processing of optical signals, reception and storage of optical data, and photoelectric functional materials. Modulation and conversion, up to photonic computing. Therefore, these third-order nonlinear optical functional materials have very important research value ...
