通过将BMP32C10和DB24C8基序连接在一起,成功地合成了一个四臂隐密体1,其中BMP32C10基序可以结合paraquat2,而DB24C8基序可以配合二苄铵盐3,尽管两者之间存在静电排斥2和3。这种碱/酸响应的超分子聚合物是通过两种主-客体相互作用进一步构建的,这两种作用发生在隐坦1和两种均相异的paraquat4和二苄铵盐5之间,类似于guest 2和guest 3。
By linking BMP32C10 and DB24C8 motifs together, a four‐armed cryptand1is synthesized successfully, in which BMP32C10 motif can bind paraquat2while DB24C8 motif can complex dibenzylammonium salt3in spite of the electrostatic repulsion between guests2and3. The base/acid‐responsive supramolecular polymer is constructed further via two kinds of host–guest interactions between cryptand1and two homoditopic paraquat4and dibenzylammonium salt5similar to guests2and3.
