RT Journal Article T1 A Dynamic and Responsive Host in Action: Light‐Controlled Molecular Encapsulation A1 Ryan, Seán A1 Barrio, Jesús del A1 Suardíaz Delrío, Reynier A1 Ryan, Daniel A1 Rosta, Edina A1 Scherman, Oren AB 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 PB Wiley SN 1433-7851 YR 2016 FD 2016 LK https://hdl.handle.net/20.500.14352/92478 UL https://hdl.handle.net/20.500.14352/92478 LA eng NO Ryan, Seán T.
