Abstract
A cadmium coordination polymer, [Cd(1,4-NDC)(L)]
n
(1), has been hydrothermally synthesized by using 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (L) and 1,4-naphthalenedicarboxylic acid (1,4-H2NDC). The complex 1 was characterized by diffraction and elemental analyses. In complex 1, the cadmium ion is distorted octahedral coordinated linking the deprotonated 1,4-NDC anion to form a two-dimensional (2D) layer, and the 2D layer are associated into 3D supramolecular structure via the strong π–π stacking interactions from the conjugated L ligands. In addition, thermogravimetry, powder X-ray diffraction, and the solid-state photoluminescent properties of complex 1 were also studied.
摘要
使用1-(1H-咪唑[4,5-f][1,10]菲啰啉-2-基)萘-2-醇(L)和1,4-萘二羧酸(1,4-H2NDC)通过水热合成了一种镉配位聚合物,[Cd(1,4-NDC)(L)]n (1)。通过衍射和元素分析对复合物1进行了表征。在复合物1中,镉离子经变形八面体配位连接去质子化的1,4-NDC阴离子形成二维层,并通过共轭L配体的强π-π堆积相互作用将二维层结合成三维超分子结构。此外,还研究了复合物1的热重分析、粉末X射线衍射和固态光致发光性质。
