Two similar fluorenyl diol hosts H1 and H2 have been employed to study their selectivity toward methylated piperidines. Crystal structures show strong similarities in the packing of these inclusion compounds, but the interesting result arises from the competition of these hosts for equimolar dimethylpiperidines (2,6DMP and 3,5DMP). H1 selects 3,5DMP, while H2 selects 2,6DMP. Packing analysis and lattice
已经使用两种相似的芴基二醇主体H1和H2来研究它们对甲基化哌啶的选择性。晶体结构在这些包合物的堆积中显示出很强的相似性,但是有趣的结果是由于这些主体竞争等摩尔的二甲基哌啶(2,6DMP和3,5DMP)。H1选择3,5DMP,而H2选择2,6DMP。堆积分析和晶格能量计算未能解释该结果,但四种主客体化合物的差示扫描量热曲线与选择性实验一致。
