Aliphatic substrates show, in comparison to aromatic substrates of similar shape, up to 60 times lower binding constants with a cyclophane bearing +N charges on the inside of the cavity; much smaller differences are observed with the same cyclophane bearing no charges in the vicinity of the substrate.
与类似形状的芳族底物相比,脂肪族底物的结合常数低60倍,而在腔体内部带有+ N电荷的环烷环糊精;在基材附近没有电荷的同一个环烷中,观察到的差异要小得多。
