We exploit the EZ photoisomerization properties of azobenzenes to alter the shape of the cavity of the macrocycle upon absorption of light. Imidazolium motifs are used as hydrogen-bonding donor components, allowing for sequestration of small molecule guests in acetonitrile. Upon E!Z photoisomerization of oAzoBox4+ the guest is expelled from the macrocyclic cavityengAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1521-3773https://doi.org/10.1002/anie.201607693open access544LightPhotochemical reactionsSupramolecular chemistryQuímica23 Química
