The [CdCl_4]^(2-) anion as a structure inducer has proved to be useful in the construction of cucurbit[n]urilmetal coordination architectures and materials. In order to better understand the role and influence of the structure inducer in Q[n] systems, we report herein the self-assembly of Q[6] solely in the presence of[CdCl_4]^(2-)anions and in the presence of both a linear cationic organic guest and [CdCl_4]^(2-)anions. X-ray diffraction analysis revealed that 1D Q[6] porous channels were formed by the noncovalent interactions between Q[6] and [CdCl_4]^(2-)anions, but the ''honeycomb effect'' was not observed in the present study.However, it seems that the ''honeycomb effect'' and the self-assembly of Q[6] with [CdCl_4]^(2-)anions can be significantly modified and switched in the presence of a linear cationic dibutylamine guest through some unusual noncovalent interactions. 展开更多
