碩士 === 國立臺灣海洋大學 === 生命科學暨生物科技學系 === 106 === Two series of metal phosphites structural were shown as follows：Zn3(BDC)0.5(DTZ)(HDTZ)(HPO3)2 B1、Co3(BDC)0.5(DTZ)(HDTZ)(HPO3)2B2. B1 and B2 had a similar structure with different metal (B1 for Zn and B2 for Co). In this paper, a highly stable Crystalline Materials is synthesized by hydrothermal synthesis method. We determine the material structure by Single Crystal X-ray Diffractometer. B1 and B2 are similar structure. DTZ (3,5-Diamino-1,2,4-triazole) and BDC (Terephthalic Acid) bonded to metal center with two compound. B1 has high thermal stability (in air Up to 400 °C) and good stability against seawater, an aqueous solution (pH = 3-11) and organic solvents under boiling conditions. This material possesses the ability to effectively remove heavy metals. The change of luminescent color is observed upon detecting heavy metals. It is expected that Crystalline Materials, with further scientific research, can be utilized as a powerful water recycle tool.
