This paper studies self-assembly of beta-cyclodextrin (beta-CD) and tri-block pluronic (PEG-PPG-PEG) in aqueous solution. It was found that they could form hollow spheres due to the formation of coil-rod beta-CD/PEG-PPG-PEG inclusion complexes. In these beta-CD/PEG-PPG-PEG complexes, the beta-CDs are preferentially stacked along the PPG block of pluronic to form rod block and PEG segments act as coil block. The assemblies of beta-CD/PEG-PPG-PEG complexes show dependence of beta-CDs concentration and temperature. Furthermore, the aggregates will disrupt upon dilution below the critical micelle concentration.
本文研究了β-环糊精（β-CD）和三嵌段普朗尼克（PEG-PPG-PEG）在水溶液中的自组装。研究发现，由于形成了螺旋-棒状β-CD/PEG-PPG-PEG 包合物，它们可以形成中空球体。在这些β-CD/PEG-PPG-PEG 复合物中，β-CDs 优先沿普朗尼克的 PPG 链堆积形成棒状嵌段，而 PEG 链段则充当线圈嵌段。β-CD/PEG-PPG-PEG 复合物的组装依赖于β-CD 的浓度和温度。此外，当稀释至临界胶束浓度以下时，聚集物会被破坏。
