The quantitative double self-sorting between the three-component rectangle [Cu()()] and the four-component sandwich complex [Cu()()()] is triggered by inclusion and release of DABCO (). The fully reversible and clean switching between two multicomponent supramolecular architectures can be monitored by fluorescence changes at the zinc porphyrin sites. The structural changes are accompanied by a huge spatial contraction/expansion of the zinc porphyrin-zinc porphyrin distances that change from 31.2/38.8 Å to 6.6 Å and back. The supramolecular interconversion was used for the highly selective detection of DABCO in a mixture of other similar compounds.
由1,4 - 二氮杂双环[2.2.2]辛烷（DABCO）的包合和释放引发了三组分矩形[Cu（ ）（ ）]与四组分三明治配合物[Cu（ ）（ ）（ ）]之间的定量双自分类。两种多组分超分子结构之间完全可逆且清晰的切换可通过锌卟啉位点处的荧光变化进行监测。结构变化伴随着锌卟啉 - 锌卟啉距离的巨大空间收缩/扩展，该距离从31.2 / 38.8 Å变为6.6 Å然后再变回原来的值。超分子相互转化被用于在其他类似化合物的混合物中对DABCO进行高选择性检测。
