设计并合成了一种新型的含联嘧啶的bola两亲分子bpym-8。联嘧啶部分允许金属-配体配位，从而影响bola两亲物的自组装。在配位之前，bpym-8在水中自组装形成球形聚集体。一个有趣的发现是，铜（II）离子与联嘧啶的配位可以诱导bpym-8的组装体从球形变为聚集体。应该注意的是，bpym-8的组装可以通过从配位中除去Cu（II）离子而可逆地转化回来。本研究发现了一种新型的bola两亲分子，它能够与金属离子配位，这可能为制备可逆可调的超分子纳米材料提供新的线索。
A new type of bolaamphiphile bearing bipyrimidine (bpym-8) has been designed and synthesized. The bipyrimidine moiety allows for metal-ligand coordination, thereby influencing the self-assembly of the bolaamphiphile. Before coordination, bpym-8 self-assembles in water to form spherical aggregates. An interesting finding is that the coordination of the Cu(II) ion with bipyrimidine can induce the assembly of bpym-8 to change from spheres to clustered aggregates. It should be noted that the assembly of bpym-8 can be reversibly converted back by removing the Cu(II) ion from the coordination. This study presents a new type of bolaamphiphile that is able to coordinate with metal ions, which may provide a new clue in fabricating reversibly tunable supramolecular nanomaterials.
