在一个反应批次中合成了具有绳状和陀螺状多种形态的周期性介孔有机硅（PMO）。从XRD图谱和TEM图像中，鉴定出PMO具有六边形对称性。形态学研究采用扫描电镜和透射电镜成像。各种形貌的产生可以部分地解释为曲率程度和由各种拓扑缺陷引起的吸积类型。提出了血小板状、棒状、针状、针状和子弹状颗粒作为次级构建单元，通过侧对侧紧密堆积形成PMO的机理。
Periodic mesoporous organosilicas (PMO) with a diversity of morphologies based on rope and gyroid shapes have been synthesized in one reaction batch. From the XRD pattern and TEM image, PMO with hexagonal symmetry was identified. Morphological investigations were carried out by SEM and TEM imaging. The generation of various morphologies could be interpreted partly in terms of the degree of curvature and the accretion type induced by various topological defects. The formation mechanism of PMO via the side-to-side close packing of platelet-, stick-, pin-, syringe-, and bullet-like particles as secondary building units was suggested.
