A new polyhedral oligomeric silsesquioxane macromer, octakis[N-(6-aminopyridin-2-yl)undecanamide-10-dimethyl-siloxy]silsesquioxane (POSS-C11-Py), containing eight diaminopyridine arms, is able to self-assemble to form a physically crosslinked polymer-like structure with good mechanical properties (tensile strength = 46.1 MPa, tensile modulus = 0.58 GPa, elongation = 49.3%) through quadruple hydrogen bonding interactions between these arms. POSS-C11-Py is the first organic/inorganic supermolecule possessing polymer-like mechanical properties as a result of self-complementary interactions, providing a potential route toward the design and fabrication of polymer-like supramolecular materials.
一种新型的多面体低聚倍半硅氧烷大分子单体，八[N-(6-氨基吡啶-2-基)十一烷酰胺-10-二甲氧基硅氧]倍半硅氧烷（POSS-C11-Py），含有八个二氨基吡啶臂，能够通过这些臂之间的四重氢键相互作用自组装形成具有良好机械性能的物理交联聚合物状结构（拉伸强度=46.1 MPa，拉伸模量=0.58 GPa，伸长率=49.3%）。POSS-C11-Py 是第一个由于自互补相互作用而具有聚合物状机械性能的有机/无机超分子，为设计和制造聚合物状超分子材料提供了一种潜在途径。
