摘　　要：以嵌段共聚物P123(EO_(20)PO_(70)EO_(20))作为模板剂,在无酸介质中利用无机盐ZrOCl_2-NaCl的协同作用合成了二维六方结构的乙烷桥联PMOs(periodic mesoporous organosilicas)杂化介孔材料,并借助高分辨透射电镜(HRTEM),小角X-射线散射(SAXS),等温N_2-吸附-脱附以及固体^(13)C CP MAS NMR和^(29)Si CP MAS NMR核磁共振技术等手段对其物性特征进行了表征。结果表明:目标产物具有高度有序的六方孔道排列和有机-无机杂化网络骨架,体现了无机盐组合在目标产物组装过程中的协同作用。Structurally ordered ethane-bridged periodic mesoporous organosilicas（PMOs） have been facilely prepared with the assistance of ZrOCl_2-NaCI salt pair using nonionic P123（EO_（20）PO_（70）EO_（20）） as the structure-directing agent,and was thoroughly characterized by advanced techniques as such SAXS, HRTEM,N_2-adsorption/desorption isotherms and solid state ^（13）C CP/^（29）Si CP MAS NMR etc..The results indicated that the present material possess highly ordered hexagonal structure and organic-inorganic hybrid network,and thus illustrating the effective function of salt pair in the assembly of PMO material under the studied synthesis system.
