(a) Reversible photodimerization of anthracene. (b) Proposed photoreaction of anthracene inside the cavity of ZIF-8. (c) Crystal structure of a ZIF-8 cavity encapsulating four molecules of anthracene. (d) UV/vis absorption spectra accompanying UV irradiation of ZIF-8 encapsulating anthracene. (e) Schematic illustration of light-induced trapping and increased reactivity of small molecules within colloidal crystals (“dynamically self-assembling nanoflasks”). (f) Electron micrographs (at different magnifications) of colloidal crystals prepared by exposing azobenzene-coated gold nanoparticles to UV light. (g) Accelerated photodimerization of 9-anthracenemethanol in the presence of photoresponsive nanoparticles. (h) Stereoselectivity in the dimerization of 9-anthracenemethanol in the presence and absence of photoresponsive nanoparticles. (i) Schematic illustration of the photoreaction of 9-(4-mercaptophenylethynyl)anthracene on a Au(111) surface. (j) Dependence of the anthracene dimerization yield on the curvature of the underlying nanoparticle. (c, d) Adapted with permission from ref (34). Copyright 2019 Wiley-VCH.
