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.

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，所得材料表现出无序或无序的多孔结构，孔壁无定形，表面积较小。今年，我们设计了新的带有芳香环的膦酸源，可以增加有效的相互作用，实现高度的介观结构有序和结晶壁。特别地，我们考虑了表面活性剂、膦酸和金属前体之间的相互作用。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，将制备好的细观结构样品用溶剂洗涤。然后对所得的介孔样品进行了详细的表征，找出了最佳的合成条件。
