研究了环糊精（CDs）诱导的多金属氧酸盐团簇PMo12O403−在浓水溶液中的独特手性变化。然后确定了所使用的无机团簇和有机CD分子之间的主客体相互作用，以维持诱导的手性。在CD的初级羟基侧的超分子包裹体被证明是调节形成的手性的关键，而诱导的手性反转是通过简单地用具有更大开口的超分子取代CD或添加竞争客体来实现的。
The distinctive chirality change of a polyoxometalate cluster PMo12O403−, induced by cyclodextrins (CDs), was investigated in concentrated aqueous solutions. The host–guest interactions between the used inorganic cluster and the organic CD molecules were then identified to maintain the induced chirality. The supramolecular inclusion at the primary hydroxyl side of CDs was demonstrated to be critical in modulating the formed chirality, while the induced chirality reversal was realized by simply substituting a CD with a supramolecule with larger opening or adding a competitive guest.
