Descripción:	18 pages. -- Figure S1. (a) Bright field STEM image of the synthesized AuNRs. (b) Bright field STEM image of the AuNR@SiO2 after the first silica-shell coating. -- Figure S2. (a) STEM micrographs of synthesized AuNR@UiO-66 composite before (left) and after (right) exposure to iodine gas at 75 °C for 3 hours. Note that the AuNRs were etched after having been exposed to the iodine. (b) STEM micrographs of the AuNR@SiO2@UiO-66 composite before (left) and after (right) exposure to iodine at 75 °C for 96 hours, confirming the stability of the silica-coated AuNRs. Scale bar: 500 nm. -- Figure S3. N2-sorption isotherm measurements at 77 K, and corresponding BET plots, for UiO-66 microbeads (a) and AuNR@SiO2@UiO-66 microbeads (b). -- Table S1. Summary of the maximum temperatures reached by each studied material upon irradiation with near-infrared lasers of different intensities. -- Figure S4. (a) Plot of time vs. temperature for AuNR@SiO2@UiO-66 microbeads irradiated for 1 minute with near infrared light at an intensity of 224 mW cm-2. (b) Thermal imaging of the UiO-66 (leftmost) when irradiated at 1000 mW cm-2, and AuNR@SiO2@UiO-66 microbeads when irradiated with an intensity of 52 mW cm-2 (left), 224 mW cm-2 (middle) and 1000 mW cm-2 (right). -- Figure S5. Thermogravimetric analysis curves for pristine UiO-66 microbeads (blue), iodineloaded UiO-66 microbeads (black), and iodine-loaded AuNR@SiO2@UiO-66 microbeads (red). -- Figure S6. (a) PXRD spectra of pristine UiO-66 (black), pristine AuNR@SiO2@UiO-66 (red), UiO-66 after desorption of iodine (blue), and AuNR@SiO2@UiO-66 after desorption of iodine (green). (b) HAADF-STEM micrograph of AuNR@SiO2@UiO-66 after 96-hour exposure to iodine at 75 °C. Scale bar: 100 nm. -- Figure S7. Release of iodine from I2@UiO-66 microbeads (black) and I2@AuNR@SiO2@UiO-66 microbeads (red), without any laser irradiation. Inset: zoomed section of graph. -- Figure S8.

TGA curves of the iodine-loaded composite films containing AuNR@SiO2@UiO- 66 microbeads at 0% (black), 8% (red), 25% (blue) and 46% (green) (w/w). -- Figure S10. Iodine release over time from the composite films containing AuNR@SiO2@UiO-66 microbeads at 46% (a) and 25% (b) (w/w), without any laser irradiation. -- Figure S11 (a) Stepwise release of iodine from a composite film containing I2@AuNR@SiO2@UiO-66 microbeads at 25% (w/w) irradiated with NIR light at 224 mW cm-2 and subjected to on/off switching.
