The diol host compound 2 featuring a structure with two 9-fluorenol moieties attached in 3,3′-position to a biphenyl core unit has been synthesized and is shown to form crystalline inclusion complexes with organic guest molecules. Aside from the single-crystal X-ray structures of unsolvated 2 in two polymorphous forms (2A, 2B), structures of five inclusion compounds with 1,4-dioxane (2a), DMSO (2b)
已经合成了具有以下特征的二醇主体化合物2,该结构具有在3,3'-位连接到联苯核心单元上的两个9-芴基部分,并显示出与有机客体分子形成结晶包含物复合物。除了未溶剂化的2的单晶X射线结构以两种多晶型(2A,2B)外,还有五种包含1,4-二恶烷(2a),DMSO(2b),二乙胺(2c),乙酸的包合物的结构(2d)和乙酸乙酯(2e)在相互作用行为中进行了描述和比较讨论,包括具有联苯单元和二苯基羟甲基取代的等价物的不同连接方式的相应主体化合物。
