For fabricating a hydrogen-bonded framework with a stabilized hybrid structure for versatile functional properties, an inorganic polyanionic cluster that bears covalently grafted organic groups for hydrogen bond connection is synthesized. By modifying two guanine groups into a disklike polyoxometalate [Mn(OH)6Mo6O18]3– on both sides symmetrically, a polyanionic hybrid building block is obtained. With
为了制造具有稳定杂化结构以实现多种功能特性的氢键框架,合成了一种无机聚阴离子簇,该簇带有用于氢键连接的共价接枝有机基团。通过将两个鸟嘌呤基团修饰成盘状多金属氧酸盐 [Mn(OH) 6 Mo 6 O 18 ] 3–在两侧对称地,获得聚阴离子杂化结构单元。以簇作为桥梁,接枝鸟嘌呤单元作为结合位点,在二维平面内以正方形晶格形状的多金属氧酸盐内置氢键框架被制成单层组件. 在进一步的步骤中,抗衡离子连接和亲水/疏水效应用于驱动层状框架组件沿垂直方向生长。由此产生的团簇嵌入框架在活化后具有永久孔隙率和内层离子特性,这使得该框架能够通过带电特性表现出对有机阳离子的高电荷/尺寸选择性吸附和甲硫氨酸的 pH 控制催化氧化。
