1H NMR, and MS spectra. Their inclusion capabilities for a variety of organic solvents were examined. It was found that substitution on the phenyl groups connected to both ends of these cumulenes critically influences their inclusion behavior since the substituents dictate the size and shape of lattice space for accommodation of the guest molecules. The crystal structures of an unsolvated butatriene
合成了一系列四芳基取代的枯草烯,并通过元素分析、1H NMR 和 MS 光谱对其进行了表征。检查了它们对各种有机溶剂的包合能力。发现连接到这些枯草烯两端的苯基上的取代会严重影响它们的包含行为,因为取代基决定了用于容纳客体分子的晶格空间的大小和形状。未溶剂化的丁三烯及其与对二甲苯和邻二甲苯的 1:2 包合物的晶体结构通过 X 射线晶体学确定。结构分析表明,客体分子不仅仅适合主体晶格的自由空间,而且它们的存在重新排列了包合物中主体分子的堆积模式。
