英文摘要： On the basis of the investigation of subsystems of B-O and Ga-O, we have synthesized the novel borogallates microporous crystal materials under mild hydrothermal, solvothermal and ionic liquids-thermal conditions, using alkali metal or alkaline earth metal ions, organic base, and transition metal complexs as templating agents. The influences of different sources materials of boron and gallium, different B / Ga ratio, solution pH, temperature and the presence of HF on the synthesized products have also studied. Twelve kinds of new microporous crystals have been obtained, which were characterized by element analysis FT-IR spectroscopy, PXRD and simultaneous TGA-DTA. Their crystal structures were determined by using single crystal X-ray diffraction. The thermodynamic properties and nonlinear optical properties of the part of the synthesized products have been investigated. The properties of ion exchange and adsorption for the synthesized microporous crystal materials with large hole have also been investigated. In this project, 21 SCI source journal papers have been published, and a patent has been applied. Two doctoral and 12 graduate students have been cultivated. We participated in domestic academic conferences for five times. The results have provided the experimental and academic foundation for screening useful novel microporous and nonlinear optical materials, enriched the types and structural chemistry of microporous materials, and had great significances for the promoting development of inorganic microporous materials continuously.
