new mesityl‐(bis or tris)imidazolium‐based alkoxysilane precursors into their corresponding bridged silsesquioxanes has been investigated. These precursors feature urea groups and either short or long alkylene chains, which are known to favor self‐assembly. The most regular nanostructures were obtained by a combination of the tripodal precursors with C10H20 alkylene chains, as shown by powder X‐ray diffraction
已经研究了通过水解/缩合将四种新的基于异丁基(双或三)咪唑鎓的烷氧基硅烷前体转化为相应的桥联倍半硅氧烷的方法。这些前体具有脲基和亚烷基短链或长链,已知有利于自组装。最规则的纳米结构是通过三脚架前体与C 10 H 20亚烷基链的组合获得的,如粉末X射线衍射(PXRD)分析所示,与反应条件无关。
