摘要: 本文设计并合成了一个具有共价有机骨架微孔结构的聚三(4-苯基)硅醇化合物。该化合物是利用乌尔曼反应,三(4-溴苯基)硅醇自聚合得到的。通过MAS NMR,FTIR,SEM,PXRD对化合物结构进行了表征。并通过TGA及氮气吸附表征化合物热稳定性及孔性质。该化合物具有高热稳定性(467 ℃失重5%),高化学稳定性,高BET比表面积(739 m2g-1)及很窄的孔径分布(1.27 nm)。

关键词: 共价有机骨架化合物, 微孔聚合物, 乌尔曼反应, 热稳定性, 化学稳定性, 羟基官能化结构

Abstract: A microporous covalent organic framework (COF) has been designed and synthesized via nickel (0)-catalyzed Yamamoto-type Ullmann cross-coupling reaction. Tri(4-bromophenyl)silanol has been employed as monomer and the structure was determined using MAS NMR, FTIR, SEM and PXRD. The functional structure exhibits not only high thermal stability (467 ℃),high chemical stability but also large surface area (958 m2g-1), and the pore size is 1.27 nm.

Key words: covalent organic frameworks(COFs), microporous polymer, Ullmann reaction, thermal and chemical stability, Chemical stability, hydroxyl functional structure
