a, b Under ultraviolet irradiation, the trifluoroacetic acid molecules overflow from the lattice and the structural symmetry is increased (The para-coordination TCNB occupied 0.5). c In situ process from SC-1 to SC-2-0.8 and SC-2-0.5. Illustration of a stabilization SC-2-0.5 of UV-induced vacancy defects in SCC-MOFs transformed from metastable SC-1; and the detailed annotation of the TCNB coordination modes in 3D-framework and 2D-network in the three compounds. d interspersed structures of SC-1 and SC-2. e The distance between Ag, S, N atoms of adjacent clusters and the vacancy TCNB and TFA. For clarity, all auxiliary ligands and hydrogen atoms are omitted. Color code: 3D frame cluster node, cyan; 2D network cluster node, gold; 1, 2, 4-coordination TCNB ligand cyan, 1, 4-coordination TCNB ligand, gold; the larger transparent gold atoms represent TCNB ligands that are not fully occupied.
