摘　　要：以笼形八聚(γ-氯化铵丙基)倍半硅氧烷(OCAPS)与丁二酸酐为原料进行了酰胺化反应,合成了笼形八聚(羧乙基羰氨基丙基)倍半硅氧烷(OCPS),产率约为60%,产物易溶于DMF(二甲基甲酰胺)和DMSO(二甲基亚砜)等强极性溶剂,微溶于水,不溶于THF(四氢呋喃)和氯仿等有机溶剂,经FT-IR、1 H-NMR和29Si-NMR验证了其化学结构。利用XRD和SEM研究了其聚集态结构,结果表明,OCPS为多晶结构,在本体状态下聚集为微米级的立方体块状颗粒;EDS能谱分析表明,OCPS的各组成元素比例与理论值接近;热重分析表明,OCPS在226℃和511℃有2次较大的失重,分别对应羧基的脱除和有机取代基的分解。Cage-like octakis （carboxyethylcarbonylaminopropyl） silsesquioxane （OCPS） was synthesized as the product of the reaction of cage-like octakis（γ-chloroaminopropyl） silsesquioxane （OCAPS） and succinic anhydride,the yield was about 60%.The product is soluble in highly polar solvents such as DMF and DMSO,slightly soluble in water and insoluble in organic solvents such as THF and chloroform.Its chemical structure was confirmed by FT-IR,1 H-NMR and 29 Si-NMR.XRD and SEM methods were used to investigate the aggregation structure of OCPS.The results showed that,OCPS had a crystal structure and aggregates in the bulk state as cubic block in micrometer scale;EDS analysis showed that,the element contents of OCPS was close to the theoretical value; TGA result showed that,OCPS has two weight loss at 226 ℃ and 511 ℃,respectively corresponding to the removal of carboxyl and the decomposition of organic substituents.
