two inclusion complexes of other two partial substituted cucurbit[6]urils, meta -hexamethyl cucurbit[6]uril ( m -HMeQ[6]) and symmetrical dicyclohexano cucurbit[6]uril ( p -(CyH) 2 Q[6]) with HCl salt of DMBPY were also reported. They were p -(CyH) 2 Q[6]- DMBPY + }Cl − 16H 2 O ( 4 ) and m -HMeQ[6]- DMBPY + }Cl − 15H 2 O ( 5 ). The driving force for the information of the host–guest inclusion complexes
摘要 使用探针客体,两种新的烷基取代葫芦 [6] 脲主体邻四甲基葫芦 [6] 脲 (o -TMeQ[6]) 和对称四环己基葫芦 [6] 脲 (TCyHQ) 的三种主客体包合物[6])已通过单晶 X 射线衍射成功表征。它们是 o -TMeQ[6]-5,5'二甲基-2,2'-双吡啶 (DMBPY) + }Cl − 21H 2 O( 1 ), ( o -TMeQ[6]) 2 -1,6 -双苯并咪唑基己烷 (SBH) 2+ } 2Cl - 52H 2 O ( 2 ) 和 TCyHQ[6]- 二恶烷 }14H 2 O ( 3 )。此外,另外两种部分取代的葫芦[6]脲的两个包合物,即间六甲基葫芦[6]脲(m-HMeQ[6])和对称的双环己基葫芦[6]脲(p-(CyH) ) 2 Q[6]) 与 DMBPY 的 HCl 盐也有报道。它们是 p -(CyH) 2 Q[6]- DMBPY + }Cl
