2 Fig. 1 Schematic representation.
Schematic representation. Schematic illustration of the synthesis of UiO-68-azo and further construction of RhB-loaded, β-CD–capped UiO-68-azo with azobenzene units as stalks encircled by β-CD on the surface. The trans-azobenzene is colored in green. Xiangshi Meng et al. Sci Adv 2016;2:e Copyright © 2016, The Authors

3 Fig. 2 Crystal structure and gas absorption behavior.
Crystal structure and gas absorption behavior. (A) Crystal structure of UiO-68-azo. The azobenzene units were not located in the electron density map and are instead presented in an optimized position. (B) N2 adsorption isotherms of activated UiO-68-azo. Xiangshi Meng et al. Sci Adv 2016;2:e Copyright © 2016, The Authors

4 Fig. 3 PXRD patterns. PXRD patterns. (A to E) Simulated from the crystal structure of UiO-68-azo (A), fresh UiO-68-azo (B), RhB-loaded, β-CD–capped UiO-68-azo (C), RhB-loaded, β-CD–capped UiO-68-azo after UV irradiation (D), and RhB-loaded, β-CD–capped UiO-68-azo after addition of amantadine and then UV irradiation (E). The patterns were taken with crystals covered by a thin layer of water. Xiangshi Meng et al. Sci Adv 2016;2:e Copyright © 2016, The Authors

5 Fig. 4 On-command release.
On-command release. (A) Schematic illustration of the light-triggered release. The cis-azobenzene is colored in cyan. (B) Release profiles of RhB-loaded, β-CD–capped UiO-68-azo by UV irradiation. Xiangshi Meng et al. Sci Adv 2016;2:e Copyright © 2016, The Authors

6 Fig. 5 Step-by-step on-command release.
Step-by-step on-command release. (A) Schematic illustration of the step-by-step release. The cis-azobenzene is colored in cyan. (B) Release profiles of RhB-loaded, β-CD–capped UiO-68-azo by addition of amantadine and then UV irradiation. Xiangshi Meng et al. Sci Adv 2016;2:e Copyright © 2016, The Authors
