中文摘要:

二三维( 3D )有 isostructures 的多孔的heterometal器官的框架( HMOF ),[ Zn 2 Cd (哦)( BTC ) 2(DMF)(H2 O ) 2]·(H3 O )( JUC-155A )并且[ ZnCo 2(OH)(BTC)2(DMF)(H2 O ) 2]·(H3 O )( JUC-155B )( JUC=Jilin 大学中国, BTC=1,3,5-benzenetricarboxylate 和 DMF=N , N-dimethylformamide ),被利用二种 3d 金属离子成功地综合了( Zn ( II )或 Zn ( II )一X 光检查晶体学表明 HMOF 由 trinuclear 金属羧化物组成第二等的大楼单位(SBU ) ,和这些 SBU 被 BTC ligands 的苯基组连结产生与大约 6.3 和 10.7 Å 的隧道的二种类型开框架的 3D。两 HMOF 在光致发光和吸附显示出多功能的性质。JUC-155B 也展出一个 antiferromagnetic 相互作用,由于 dinuclear 钴中心的存在。另外, JUC-155A 的高压的氢存储也在 77 K 被检验了。由在聚类的 SBU 使用混合金属中心,与 heterometallic 系统构造那些 isostructures 是好策略,并且如此的 HMOF 的存在将进一步便于多功能的材料的探索,这被相信。

英文摘要:

Two three-dimensional (3D) porous heterometal-organic frameworks (HMOFs) with isostructures, [Zn2Cd(OH)(BTC)2(DMF)(H20)z].(H30) (JUC-155A) and [ZnCo2(OH)(BTC)z(DMF)(H2O)2].(H3O) (JUC-155B) (JUC = Jilin University China, BTC = 1,3,5-benzenetricarboxylate and DMF = N,N-dimethylformamide), have been successfully synthesized by utilizing two kinds of 3d metal ions (Zn(II) and Cd(II) or Zn(II) and Co(II)) under conformable conditions. X-ray crystallography reveals that both HMOFs consist of trinuclear metal-carboxylate secon- dary building units (SBUs), and these SBUs are interlinked by the phenyl groups of BTC ligands to generate 3D open-frameworks with two types of channels of about 6.3 and 10.7 A.. Both HMOFs show the multifunctional prop- erties in photoluminescence and adsorption. JUC-155B also exhibits an antiferromagnetic interaction, owing to the presence of dinuclear cobalt centers. Additionally, the high-pressure hydrogen storage of JUC-155A has been also examined at 77 K. By using mixed metal centers in clustered SBUs, it is a good strategy to construct those isostructures with heterometallic systems, and it is believed that the presence of such HMOFs will further facilitate the exploration ofmultifunctional materials.
