英文摘要: This research project of Zintl chemistry mainly deals with the syntheses, structures and reactivities of naked clusters anions built of heavy main-group elements and transition (rare earth) metals. Probing the high-temperature solid state syntheses, solid state structures and solution chemistry of novel K-M-Pn ternary Zintl phases(M = transition (rare earth) metals; Pn = Sb, Bi) will be one of the main research programs, armed at understanding theoretical rules governing the formation of the solid state structures, structural rearrangement in solution and the reactivity towards varied organometallic reagents. The chemical reactions between group 14 Zintl ions and metal carbonyl clusters/multiply bonded organometallic species will be the second main research program to develop a new type of Zintl-carbonyl hybridized clusters and new oxidative coupling in the presence of metal crbonyl clusters, establishing frantier interdiscipline: Zintl-organometallic cluster chemistry. This research project is also armed at preparing nano-sized semiconducting porous materials by employing bottom-up method, namely surfactant-directed oxidative coupling of Zintl anion precursors, and exploring their adsorption of dye-sensitized molecules, providing platform for advanced highly efficient dye-sesitized solar cell.
