The complexation behavior of pillar[6]arene hosts towards a carbonium ion, tropylium tetrafluoroborate (T·BF4), and the formation of novel charge-transfer (CT) inclusion complexes are described. In contrast, smaller pillar[5]arenes and larger pillar[7]arenes cannot form such complexes due to the unsuitable cavity dimensions.
描述了杯[6]芳烃主体与碳正离子、四氟硼酸𬭩(T·BF4)的络合行为以及新型电荷转移(CT)包络复合物的形成。相比之下,较小的杯[5]芳烃和较大的杯[7]芳烃由于空腔尺寸不合适,无法形成这样的配合物。
