00925njm 22002777a 4500 dc Ryan, Seán author Barrio, Jesús del author Suardíaz Delrío, Reynier author Ryan, Daniel author Rosta, Edina author Scherman, Oren author 2016 The rational design of a flexible molecular box, oAzoBox4+ , incoporating both photochromic and supramolecular recognition motifs is described. 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 cavity Ryan, Seán T.
