Highly porous organosilicas were synthesized via direct co-condensation of two monomers, bis (triethoxysilyl) benzene and aminopropyltriethoxysilane, by adjusting the time between consecutive additions of the monomers and the ageing time of the as-obtained samples. The resulting organosilicas exhibited high porosities, with total pore volumes exceeding 2.2 cm/g. Alongside detailed insights into the morphology, structure, and surface chemistry via a broad spectrum of various instrumental techniques, the obtained ultraporous amine-functionalized organosilicas were tested as adsorbents of diclofenac sodium, chosen here as a model drug. The results revealed remarkable differences in the physicochemical properties and adsorption efficiencies among the obtained samples, confirming that the time gap between the addition of the monomers and ageing time can be used to tune the morphological, structural, and chemical features of the obtained organosilicas and, as a consequence, their sorption efficiencies.
通过双（三乙氧基硅基）苯和氨丙基三乙氧基硅烷这两种单体的直接共缩聚反应，通过调整单体连续添加之间的时间以及所得样品的老化时间，合成了高度多孔的有机硅。所得有机硅表现出高孔隙率，总孔体积超过2.2 cm/g。除了通过广泛的各种仪器技术对形态、结构和表面化学进行详细研究外，还对所得的超多孔胺功能化有机硅作为双氯芬酸钠的吸附剂进行了测试，此处选择双氯芬酸钠作为模型药物。结果表明，所得样品在物理化学性质和吸附效率方面存在显著差异，证实了单体添加与老化时间之间的时间间隔可用于调节所得有机硅的形态、结构和化学特征，从而调节其吸附效率。
