顺式十氢萘(2)和二萘嵌苯(3)在自组装的M_6L_4配位笼(1)的作用下共包合,得到1 π(2·3),尽管它们都没有被包合.这种现象被称为AND双分子包合,因为包合只有在2和3共存时才会发生。笼1还包合了甘菊环(8)和1,4-萘醌(9),得到1.8(8·9)。在这种情况下,1 <$(8)2和1 <$(9)2是分别用8和9处理1而形成的。这种情况被称为OR双分子聚合,因为如果存在8或9,就会发生包合。因此,我们已经表明,自组装笼1的经验和或双分子识别。
cis-Decalin (2) and perylene (3) are co-enclathrated by a self-assembled M6L4-coordination cage (1) to give1⊃(2·3) although each of them is not enclathrated. This phenomenon is termed asANDbimolecular recognitionbecause enclathration occurs only if2and3coexist. Cage1also coenclathrates azulene (8) and 1,4-naphthoquinone (9) to give1⊃(8·9). In this case,1⊃(8)2and1⊃(9)2are formed by treating1with8and9individually. This case is termed asOR bimolecular recognitionbecause enclathration occurs if8or9exists. Accordingly, we have shown that the self-assembled cage1experiences both AND and OR bimolecular recognition.
