By linking BMP32C10 and DB24C8 motifs together, a four‐armed cryptand 1 is synthesized successfully, in which BMP32C10 motif can bind paraquat 2 while DB24C8 motif can complex dibenzylammonium salt 3 in spite of the electrostatic repulsion between guests 2 and 3. The base/acid‐responsive supramolecular polymer is constructed further via two kinds of host–guest interactions between cryptand 1 and two homoditopic paraquat 4 and dibenzylammonium salt 5 similar to guests 2 and 3.

四臂不对称密码子：从两个不同的主客互动到响应性超分子聚合物

通过将BMP32C10和DB24C8基序连接在一起，可以成功合成四臂穴状配体1，尽管来宾2和3之间有静电排斥，但BMP32C10基序可以结合百草枯2，而DB24C8基序可以使二苄基铵盐3络合。碱/酸响应性超分子聚合物是通过隐体1和两个同位异百草枯4和二苄基铵盐5之间的两种客体-客体相互作用进一步构建的，类似于来宾2和3。
