Solution NMR studies of the interaction between the hexanucleotide d(GTCGAC)(2), β-cyclodextrin and a boronated 2,2':6',2''-terpyridineplatinum(II) complex containing 1,12-dicarba-closo-dodecaborane(12) (1,12-closo-carborane) reveal the formation of a remarkable ternary supramolecular system in which the terpyridine ligand is intercalated between the C(3) and G(4) bases, whilst the closo-carborane moiety is encapsulated by the cyclic sugar.
通过溶液核磁共振研究发现，六核苷酸 d(GTCGAC)(2)、β-环糊精与硼化 2,2':6',2''-三联吡啶铂(II)配合物（含有 1,12-二碳杂-closo-十二硼烷(12)（1,12-closo--carborane））之间存在相互作用，形成了一个显著的三元超分子体系，其中三联吡啶配体插入在 C(3)和 G(4)碱基之间，而 closo-carborane 部分被环状糖包裹。
