A covalent organic cage embedding a single inward-facing halogen-bond (XB) donor enables recognition of DMMP, a Sarin surrogate, with atomic precision through halogen bonding, while both the hydrogen...

In order to enhance the recognition properties of a given substrate, to increase the stability of an intermediate or to sequester a pollutant from its medium, the development of suitable confined spac...

Recent advances in the generation of ultrashort, few-femtosecond laser pulses in the ultraviolet–visible domain are now enabling the coherent excitation of several electronic states in neutral molecul...

The synthesis of neutral-electron-deficient molecular containers is highly challenging. Nonetheless, the presence of π-acidic units within the confined space of a molecular cage should enable strong anion binding through synergistic anion-π interactions. Here, we report the synthesis of a neutral molecular cage containing five electron-deficient units: two benzene triimide units as roof and floor and three naphthalene diimide units as walls. The study of the cage’s conformational isomerism is presented together with the high affinity of the receptor for acetate.
