a The crystal structure of Zn-IPA MOF. b PL spectra of Zn-IPA at 1 atm irradiated by 355 nm laser. c The time-resolved PL decay curves of the pristine Zn-IPA measured at 417 nm and 508 nm, respectively. d The PL evolution of Zn-IPA upon compression. e PL spectra of Zn-IPA after completely releasing pressure from 20.2 GPa irradiated by 355 nm laser. f The CIE color coordinates of Zn-IPA-11 (0.21, 0.21) and Zn-IPA-20 (0.29, 0.37). g PL spectra of Zn-IPA at 1 atm, after completely releasing pressure from 11.4 GPa (Zn-IPA-11) and 20.2 GPa (Zn-IPA-20) irradiated by 355 nm laser. h Photographs of the pristine Zn-IPA (1 atm), Zn-IPA-11, and Zn-IPA-20.
