Proazaphosphatranes (also named Verkade's superbases) and their azaphosphatrane conjugated acids have been recently been shown to be confined in either covalent or self-assembled molecular cages, or immobilized in nanopores of hybrid materials. The encapsulation of these phosphorus moieties turns out to strongly affect both their acid-base, catalytic, and recognition properties. The thermodynamics and kinetics of the proton transfer as well as the selectivity and catalytic activities of Verkade's superbases were strongly changed upon their confinement in a hemicryptophane cavity. Moreover, self-assembled cages, including azaphosphatrane moieties, were found to display remarkable anion recognition properties in water. In this Minireview, these new aspects of the chemistry of aza- and proaza-phosphatranes are presented, in order to highlight the great potential of such an approach.

密闭空间中氮杂磷酰胺和原磷杂戊酸酯的封装。

最近已显示，原磷酰胺（也称为Verkade的超碱）及其氮杂磷杂环戊烷共轭酸被限制在共价或自组装分子笼中，或固定在杂化材料的纳米孔中。事实证明，这些磷部分的封装会强烈影响其酸碱，催化和识别特性。质子转移的热力学和动力学以及Verkade的超碱的选择性和催化活性在其被限制在半色氨酸腔中时发生了很大变化。此外，发现包括氮杂磷杂环戊烷部分的自组装笼子在水中显示出显着的阴离子识别特性。在此Minireview中，介绍了氮杂和原杂戊型磷酸酯化学的这些新方面，
