The long alkyl chain of N,Nâ²-bis(4-dimethylaminobenzyl)dodecane-1,12-diamine (C12DA) adopts different chiral helical conformations, one left-handed and the other right-handed, when bound within the cavities of two distorted cucurbit[8]uril (Q[8]) units, as unequivocally established by X-ray crystallography.
N,N-2-双(4-二甲基氨基苄基)十二烷-1,12-二胺 (C12DA) 的长烷基链在结合在X 射线晶体学明确确定了两个扭曲的葫芦[8]尿素 (Q[8]) 单位。
