      摘要

      中文摘要 光誘導磁性轉變材料在信息存儲、磁共振成像等領域具有重要應用。多氰基配合物被認為是最有發展前景的光誘導磁性轉變材料,但已報道的光誘導磁化現象絕大多數是發生在冰點以下溫區。因此,獲得室溫下具有光誘導磁化效應的材料仍然是光化學和磁學領域的一個科學難題,也是其走向應用的關鍵。申請人曾成功獲得一個具有顯著室溫光誘導磁化效應的氰基配合物(JACS,2015)。在此基礎上,本項目致力于闡明多氰基化合物結構與光誘導磁化效應的構效關系,揭示其在室溫而不是冰點以下表現光誘導磁化效應的結構本質,為發展具有室溫光誘導磁化效應的多氰基化合物,建立適用性廣、可靠性強的結構設計方法。擬通過組份調控和不同實驗方法合成幾個系列多氰基配合物,結合多種譜學手段探討各組份和晶體結構對光誘導磁化性能的影響;以具有室溫光誘導磁化效應的孤立結構化合物為研究模型,用理論計算探討光產物在室溫下穩定存在的原因。預計發表6-8篇論SCI論文。
      英文摘要 Photoinduced magnetic change (photomagnetic) material has important applications in the information storage, magnetic resonance imaging, and other field. Polycyanometallate compounds are considered to be the most promising photomagneticmaterials. However, most of them show photomagnetism below the freezing temperature. It is still a challenge to obtain significant photomagnetic materials at room temperature in the field of photochemistry and magnetism. It is also a key to practical application. We have successfully obtained a hexacyanoferrate with photomagnetism at room temperature (JACS, 2015). Based on this, this project intend to elucidate the relationship between structure and properties, to reveal reason why Polycyanometallate compounds can show photomagnetism at room temperature rather than freezing point with the theoretical calculation method, in order to provid structural desigen method with wide applicability and high reliability for developing the photomagnetic materials at room temperature. Firstly, by using different composition and method, we will synthesize several series of crystalline Polycyanometallate compounds with photomagnetism at room temperature. Then, we will analyze the influence of components and crystal structure on photomagnetic properties. Finally, by selecting the appropriate theory model, we plan to explore the reasons of the stability of light product at room temperature. The research results are scheduled to appear in about 6-8 journals.
