Abstract：
Reasonable yields of two dendrimers with central tetraphenylmethane and peripheral 3,5-di-(tert-butanoylamino)benzoylpiperazine moieties are prepared. These dendrimers have a void space in the solid state so they adsorb guest molecules. Their BET values vary, depending on the H-bond interaction between the peripheral moiety and the gas molecules, and the dendritic framework that fabricates the void space is flexible. In the presence of polar gas molecules such as CO2, the BET increases significantly and is about 4-8 times the BET under N2. One dendrimer adsorbs cyanobenzene to a level of 436 mg/g, which, to the authors\' best knowledge, is almost equivalent to the highest reported value in the literature.
摘要：
制备了具有中心四苯基甲烷和外围3,5-二-（叔丁酰基氨基）苯甲酰基哌嗪部分的两个树枝状聚合物的合理产率。这些树枝状聚合物在固态下具有空隙空间,因此它们吸附客体分子。他们的BET值各不相同，取决于外围部分和气体分子之间的H键相互作用，构成空隙空间的树枝状框架是柔性的。在极性气体分子如CO2的存在下,BET显著增加并且是N2下BET的约4-8倍。一种树枝状聚合物吸附氰基苯的水平为436mg/g，which,对于作者最好的知识，几乎相当于文献中的最高报道值。
