Additionally, the crystal density of 2(DED)·4-MA (1.335 g·cm–1) was greater than those of 2(DED)·3(ANI) (1.277 g·cm–1), 2(DED)·2-MA (1.257 g·cm–1), and 2(DED)·3-MA (1.283 g·cm–1), alluding to a tighter packing in the complex with the preferred guest species owing to the shorter contacts in this crystal. The higher density was also explained by a significantly shorter intermolecular (host)π···π(host) interaction
trans -9,10-Dihydro-9,10-ethanoanthracene-11,12-dicarboxylic acid ( DED ), 二甲基trans -9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboxylate ( H1 ), and trans -α,α,α',α'-tetraphenyl-9,10-dihydro-9,10-ethanoanthracene-11,12-dimethanol ( H2 ) 与苯甲醚 (ANI) 和 2-, 3-, 4- 形成络合物单溶剂重结晶实验中的甲基苯甲醚(2-、3- 和 4-MA)。当从等摩尔二元、三元和四元混合物 (82.2–99.3%) 和存在该客体的非等摩尔二元溶液中重结晶时,观察到DED对 4-MA 具有压倒性的选择性。因此证明了DED可以作为一种有效的宿主化合物,用于分离
