通过水热合成得到3个有机金属配位聚合物,即[Cu(1,2-BDC)(L)](1),[Cu(HBTC)(L)]·2H2O(2),[Co(HBTC)(L)]·H2O(3),(L=N,N-双(3-氨基吡啶)乙二酰胺,1,2-H2BDC=1,2-邻苯二甲酸和H3BTC=1,3,5-均苯三甲酸)。配合物1是基于1D[Cu-1,2-BDC]n和[CuL]n链形成的一个3DCdSO4-型拓扑结构。配合物2~3是同构的,均显示出2D双层(3,5)-连接的{42·67·8}{42·6}拓扑结构。相邻的2D双层网络通过分子间的氢键(配合物2)和π-π堆积(配合物3)作用进一步拓展成3D超分子框架。我们对芳香羧酸和中心金属离子对配合物结构的影响进行了详细的讨论。此外,还研究了配合物1~3的电化学性质和固态荧光性质。
Three organometallic coordination polymers [Cu (1,2-BDC) (L)] (1), [Cu (HBTC) (L)] · 2H2O (2) and [Co HBTC) (L)] • H2O (3), (L = N, N-bis (3-aminopyridine) ethanediamide, 1,2-H2BDC = 1,2-Phthalic acid and H3BTC = 1,3 , 5-trimesic acid). Complex 1 is a 3DCdSO 4 -type topology based on 1D [Cu-1,2-BDC] n and [CuL] n chains. The complexes 2 ~ 3 are isomorphic and all show the 2D bilayer (3,5) -linked {42 · 67 · 8} {42 · 6} topology. The adjacent 2D bilayer network further expands into a 3D supramolecular framework by means of the intermolecular hydrogen bonding (Complex 2) and π-π stacking (Complex 3). We discuss the effects of aromatic carboxylic acids and central metal ions on the structure of complexes. In addition, the electrochemical properties and solid-state fluorescence properties of complexes 1 ~ 3 were also studied.
