様々な金属を用いたメソポーラスMetal Phosphonate物質の新合成

在某些情况下，由于磷酸前体脂肪链之间缺乏分子间相互作用，所得材料呈现出无序/无序的多孔结构，孔壁无定形，比表面积较小。在这一年里，我们设计了新的含芳环的膦酸源，并可以增加有效相互作用，实现高度介观结构的有序化和结晶化壁面。特别是，我们考虑了表面活性剂、磷酸和金属前驱体之间的相互作用。我们使用十六烷基三甲基溴化铵(CTAB)、低聚表面活性剂(C16EO10、C16EO20)和三嵌段共聚物(EO80PO30EO80、EO106PO70EO106和EO20PO70EO20)作为结构导向剂。为了去除模板，制备的介孔样品用溶剂洗涤。之后，我们对得到的介孔样品进行了仔细的表征，找出了最佳的合成条件。

In some cases, the obtained materials showed less-ordered/dis-ordered porous structure with the amorphous pore walls and less surface area, due to the lack of intermolecular interaction between aliphatic chains of phosphonic acid precursors. In this year, we designed new phosphonic acid sources with aromatic rings, and could increase effective interaction to realize highly mesostructural ordering and crystalized walls. Especially, we considered the interaction between surfactants, phosphonic acids, and metal precursors. We used cetyltrimethylammonium bromide (CTAB), oligomeric surfactants (C16EO10, C16EO20), and triblock copolymers (EO80PO30EO80, EO106PO70EO106, and EO20PO70EO20) as structure-directing agents. To remove the templates, as-prepared mesostructured samples were washed with solvents. After that, we carefully characterized the obtained mesoporous samples and we could find out the optimal synthetic conditions.
