中文摘要
为了进一步研究配位基团的位置的不同和配体刚柔性对配位聚合物自组装的影响,我们设计并合成了两个新型的柔性四齿配体:L1[1,2-bis(3'-pyridylmethylamino)ethane]和L2[1,2-bis(3'-pyridylmethyleneamino)ethane]。L1的柔性要略大于L2。通过L1和Cd(NO3)2,L2
和CF3SO3Ag,L2和Zn(SCN)2的反应。我们得到了三个新型的配位聚合物,分别为[Cd(L1)](NO3)2·H2O,[Ag2(L2)2](CF3SO3)2 ,[Zn(L2)2](SCN)2·2H2O。它们依次为一维链状,二维网状和三维结构。利用X-Ray单晶衍射对晶体进行解析,同时还利用ESMS和荧光光谱进一步验证,从而验证了配位基团的位置的不同和配体刚柔性对配位聚合物自组装的影响。

Coordination group in order to further research the location of the different ligands and just the flexible impact on coordination polymer self-assembly, we designed and synthesized two novel flexible teradentate ligand: L1 [1, 2 - bis (3 '- pyridylmethylamino) ethane] and L2 [1, 2 - bis (3' - pyridylmethyleneamino) ethane). L1 flexible slightly greater than the L2. By L1 and Cd (NO3) 2, L2
And CF3SO3Ag, L2 and zinc (SCN) 2. We got three new coordination polymer, respectively [Cd (L1)] (NO3) 2 · H2O, [hf-solvated Ag2 (L2) 2] (CF3SO3) 2, [zinc (L2) 2] (SCN) 2 · 2 H2O. They are followed by a one-dimensional chain, 2-d mesh and 3 d structure. Crystals to make use of X - Ray single crystal diffraction analysis, at
the same time also further validation by ESMS and fluorescence spectrum, thus verified plexing ligands and position of different functional groups just flexible impact on coordination polymer self-ass
