A new synthetic approach for substitutional solid solutions in a 3D coordination polymer: Cation vacancy, and tunable photoluminescence

Lead–Organic Frameworks Containing Trimesic Acid: Facile Dissolution–Crystallization and Near-White Light Emission

“…Hydro- and solvothermal synthetic methods are convenient techniques for preparing metal–organic frameworks (MOFs) using aromatic dicarboxylic acid based ligands and transition elements, in particular, post-transition elements, with reported applications such as gas storage, − magnetic, ,,, and luminescent applications. ,,− The dissolution–crystallization method, a rather less popular technique and yet requires less synthetic equipment, could potentially produce a new, kinetically stable MOF that may merit its own structural library and applications. − By a similar token of a facile dissolution–(re)-crystallization technique, postsynthetic modification of MOFs exploits the relatively weak coordination bond of certain metal centers to synthesize new compounds with tunable properties that are not possible through conventional synthetic pathways. , …”

“…11−41 By a similar token of a facile dissolution−(re)-crystallization technique, postsynthetic modification of MOFs exploits the relatively weak coordination bond of certain metal centers to synthesize new compounds with tunable properties that are not possible through conventional synthetic pathways. 42,43 Benzene-1,3,5-tricarboxylic acid (H 3 BTC) ligand, with or without a coligand, is one of the most frequently used ligands to construct MOFs, including the world-famous HKUST-1, Cu 3 (BTC) 2 (H 2 O) 3 . To date, HKUST-1 has been reported for catalytic, photocatalytic, enzyme encapsulation, and semiconducting applications.…”
