Three pillar[n]arenes (n = 8-10) were synthesized. X-ray analysis demonstrated that, different from early reported small pillar[n]arenes (n = 5, 6), these larger macrocycles gave rise to two cavities. (1)H NMR and MS experiments revealed that pillar[9]arene complexed one n-octyltrimethyl ammonium in chloroform, while pillar[10]arene could complex two.
三种(n = 8-10)柱[n]芳烃被合成。X 射线分析表明,与早期报道的较小的柱[n]芳烃(n = 5,6)不同,这些较大的大环化合物产生了两个空腔。(1)H NMR 和 MS 实验表明,在氯仿中,柱[9]芳烃络合了一个正辛基三甲基铵,而柱[10]芳烃可以络合两个。
