a Schematic synthesis of ZW-UiO-67 and ZW-UiO-67·HA. (HA = MSA, TFSA, TFA; MSA = methylsulfonic acid, TFSA = N,N-bis(trifluoromethanesulfonyl) amide, TFA = trifluoromethanesulfonic acid). b Transition of crystalline ZW-UiO-67·HA to glassy agZW-UiO-67·HA, then back to crystalline agrZW-UiO-67·HA through melting, quenching and solvent stimulation processes. The purple sphere and gray bond denote the Zr6O4(OH)4 node and BPDC-MIMS linker (BPDC = biphenyl-4,4’-dicarboxylate; MIMS = (1-methyl-3-imidazolio)propane-3-sulfonate), respectively. Parent UiO-67 assembled by BPDC is shown in Supplementary Fig. 1 for comparison.
