Periodic mesoporous organosilicas (PMOs) are a new class of organic-inorganic hybrid materials with high surface area, narrow pore size distribution, high functional group loading, and tunable functional groups. In contrast to other porous organosilicate materials, PMOs show a uniform distribution of organic groups inside their framework walls. They are synthesized by condensing bis-silylated organic precursors around a surfactant template. Their application severely depends on textural features like pore structure, particle size, porosity and surface area. This study focuses on the application of PMOs in trace determination of pesticides, while the structural features of these interesting materials are strongly considered.

含苯并咪唑的基于双峰 UVM-7 的周期性介孔有机硅，用于气相色谱-质谱法前果类蔬菜中三唑类杀菌剂的薄膜微萃取


周期性介孔有机硅 （PMO） 是一类新型有机-无机杂化材料，具有高表面积、窄孔径分布、高官能团负载和可调官能团。与其他多孔有机硅酸盐材料相比，PMO 在其框架壁内显示出有机基团的均匀分布。它们是通过在表面活性剂模板周围缩合双硅烷化有机前体来合成的。它们的应用在很大程度上取决于结构、颗粒大小、孔隙率和表面积等结构特征。本研究重点研究了 PMOs 在农药痕量测定中的应用，同时重点考虑了这些有趣材料的结构特征。
