Four new host compounds of dumbbell shape featuring bulky 2,3,4,5-tetraphenylcyclopenta-2,4-dien-1-ol moieties attached to both ends of a linear spacer element of different lengths comprising both 1,4-phenylene and ethynylene subunits are synthesized and corresponding crystal inclusions involving DMSO, DMF, MeCN, and THF as guest solvents (seven examples of inclusion compounds) are isolated.

四种新的哑铃状主体化合物,其特征在于笨重的2,3,4,5-四苯基环戊-2,4-二烯-1-醇基团连接到不同长度的线性间隔基元件的两端,包括1,4-亚苯基和亚乙炔合成两个亚基,并分离出包含DMSO,DMF,MeCN和THF作为客体溶剂的相应晶体包裹体(包裹体化合物的七个例子)。X射线结构分析表明,1:2主体/客体的形成是晶体包裹体的基本超分子基序。然而,在大多数内含物物种的情况下,似乎需要额外的溶剂分子来稳定晶体结构,这表明所含溶剂的化学计量比异常高,这是新型宿主分子的特定特征。
