Polyhedral carboxymethyl carborane (C2B10H12) derivatives, including mono‐ and disubstituted o‐, m‐, and p‐isomers, have been synthesized. Supramolecular host–guest complexation of these derivatives with cyclodextrins (CDs; namely, α‐, β‐, and γ‐CD) has been investigated in water. The globular structure of the carborane binding moiety and its hydrophobic character qualify it as an ideal recognition
已合成了多面体羧甲基碳硼烷(C 2 B 10 H 12)衍生物,包括单和双取代的o-,m-和p-异构体。这些衍生物与环糊精(CD;即α-,β-和γ-CD)的超分子主客体络合物已经在水中进行了研究。碳硼烷结合部分的球状结构及其疏水特性使其成为理想的识别位点,可与水溶液中的大环主体分子形成稳定的包合物。碳硼烷衍生物的结合亲和力在毫摩尔范围内(K a = 10 3 –10 4 m-1)具有不同大小的CD,并优先绑定到β-CD。
