介孔有机硅（MO）代表了一类有前途的有机-无机纳米复合材料，用于广泛的应用，如催化，传感，分离或微电子学。它们的显著特征是在介孔结构的通道壁中存在有机基团。在这里，我们提出了一个方便的“所有功能于一身”的方法，使用倍半硅氧烷表面活性剂前体的通道壁与伯胺基团的官能化。该单体通过基于商业单体的硼氢化/氨解序列制备，其中模板通过硼氢化结合到官能化位点，并在二氧化硅缩合和氨解后释放。这种组合确保了胺基团仅沿着通道界面放置以及模板的最佳使用。
Mesoporous organosilicas (MOs) represent a promising class of organic–inorganic nanocomposites for a broad range of applications like catalysis, sensing, separation, or microelectronics. Their distinct feature is the presence of organic groups incorporated into the channel walls of a mesoporous structure. Here, we present a convenient “all-in-one” approach using silsesquioxane surfactant precursors for the functionalization of the channel walls with primary amine groups. The monomer is made by a hydroboration/aminolysis sequence on the base of a commercial monomer, with the template bound to the functionalization site by hydroboration and released after silica condensation and aminolysis. This combination ensures both the placement of the amine groups exclusively along the channel interface as well as optimal use of the template.
