| 摘要: 通过水热反应合成了1个二维层状结构的铅配位聚合物,[Pb(4-NPA)(H2O)]n(1)(4-H2NPA=4-硝基邻苯二甲酸)。对化合物1进行了红外光谱、元素分析、热重性质以及单晶、粉末X射线衍射表征。在化合物1中,有机配体4-NPA2-阴离子采用(κ1-κ1)(κ2-κ2)-μ4桥连方式连接了4个Pb(Ⅱ)离子形成一维链状结构,该链状结构再通过1个羧酸基团形成一个二维无机层结构。利用"自上而下"的方法将该化合物在甲醇中进行了剥离实验。此外,我们还研究了化合物1的块状样品、剥离样品以及分散在甲醇中的样品的荧光性质。 |

| Abstract: Anovel coordination polymer, [Pb(4-NPA)(H2O)]n(1) (4-H2NPA=4-nitrophthalic acid) with 2Dlayered structure was obtained via a hydrothermal reaction. Compound b>1 has been characterized by IRspectroscopy, elemental analysis, thermogravimetric analysis, single-crystal and powder X-ray diffraction analysis. In b>1, the 4-NPA2-anion connects four Pb(Ⅱ) ions with its carboxylate groups in a (κ1-κ1)(κ2-κ2)-μ4-bridging mode, forming a one-dimensional chain structure running along the a axis through the oxygen atoms of the carboxylate groups. The neighboring chains are connected through the O-C-Obridges, resulting in an undulating inorganic layered structure in the ab plane. The layers of b>1 can be exfoliated in the methanol using a "top-down" approach. The bulk sample of b>1, and the exfoliated sample of b>1 as well as its dispersion solution show luminescent properties. |
