設計合成結構穩定之新穎結晶固態材料一直是熱門的研究主題，因為這些化合物不僅包含豐富結構化學等學術研究還衍生有趣物理與化學等應用性質的探討。近幾年，我們也專注於穩定晶體化合物的合成、結構鑑定與性質研究：初步研究成果顯示結合高價數無機含氧酸根於鋅金屬－含氮配位基系統（利用軟酸與軟鹼配對鍵結）可以置備結構穩定的有機無機複合結晶固體，並可以應用這些材料於環境污染防治的研究，例如，實驗室得到耐高溫及抗沸騰氫氧化鈉水溶液與有機溶劑的化合物；一些有趣結構的晶體固體還可以作為水中劇毒汞金屬離子或有機染劑分子的吸附劑。未來，我們將持續研究工作於結構穩定之新穎鋅金屬結晶材料的合成與開發，並使用後修飾法改變材料粉體尺寸大小、內部結構或表面性質以擴展晶體化合物潛在應用的研究，此外，我們也希望可以結合固態晶體化合物及高分子來製作新型式複合材料修飾電極以作為偵測汙染的應用（目前實驗室製作的電極可以偵測10-11 M級數的汞離子濃度）。我們相信實驗室近幾年累積的合成經驗與研究成果將有助於未來專題研究計畫的執行，預期相關研究成果對固態化學領域與國內學術研究會有重要的影響及貢獻度。 Design and synthesis of new crystalline frameworks with stable structures have been a subject of intensive research not only because of the rich structural chemistry but also because of their chemical and physical properties. Recently, we have been also focusing on the topic of the synthesis, structural characterization, and application studies for new and stable structures. The preliminary results indicated that the incorporation of inorganic building units with high valance (such as phosphate, phosphite, and germanate) into the system containing zinc metals and nitrogen-based ligands (matching soft acids with soft bases) lead to the generation of high stable frameworks, which can be used for the studies of pollution prevention and environmental remediation. For example, several crystalline materials we synthesized exhibited not only high thermal and chemical stabilities but also the removal abilities for toxic mercury cations and organic dyes. In future, we are going on the synthesis and development of stable crystalline Zn-based materials. The particle sizes, inner structures, and surface properties of those materials can be tuned by post-synthetic modifications for expending the applications of crystalline solids. In addition, hybrid polymer/crystalline framework sensors with the high sensitivity detection for toxic metal cations have been manufactured (with a 10-11 M level for mercury cations). The recent research results and the accumulate experiences in the field of material synthesis will help the implementation of future projects. We believe this study will be of considerable interest to the inorganic and material chemistry communities.
