Heterometallic Organic Frameworks Built from Trinuclear Indium and Cuprous Halide Clusters: Ligand-Oriented Assemblies and Iodine Adsorption Behavior

Abstract

Two novel heterometallic organic frameworks built from trinuclear indium and cuprous halide clusters, 2), where Hina = isonicotinic acid, have been successfully constructed with the orientation of the ina ligand. 1 shows a fascinating highly porous honeycomb-like 3D cationic framework with a trigonal-bipyramid-type cage based on a planar [In 3 O(CO 2 ) 6 ] + trimer and a rhombohedral Cu 2 I 2 cluster. Comparably, 2 displays a 3D negative network with irregular hexagonal channels constructed from a [In 3 (OH) 2 (CO 2 ) 8 ] − trimer and a cubane-like Cu 4 I 4 cluster. Especially, 1 displays a reversible I 2 adsorption/release performance with high adsorption capacity, whose mechanism has been disclosed by theoretical simulation. Also, the green/red emission of 2 stems from iodocuprate centers with quenched indium-centered emission.

Nickel(II) Coordination Polymers Supported by Bis-pyridyl-bis-amide and Angular Dicarboxylate Ligands: Role of Ligand Flexibility in Iodine Adsorption

“…The ability of the CPs to accommodate iodine molecules in the interchain/interlayer space perhaps governs the iodine adsorption capacity [ 16 , 17 , 18 ]. The solvent accessible volumes calculated by using the PLATON program [ 19 ] for 7 – 9 were 6.9, 9.3 and 13.7%, respectively, of the unit cell volume, indicating that the 2D 9 may accommodate more iodine than the 1D 7 and 8 .…”

Dicarboxylate‐Induced Structural Diversity of Luminescent Zn(II)/Cd(II) Metal–Organic Frameworks Based on the 2,5‐Bis(4‐pyridyl)thiazolo[5,4‐d]thiazole Ligand

“…As a kind of distinctive ordered porous materials, metal‐organic frameworks (MOFs) have attracted considerable attention in the past decades. Apart from their intriguing structures, the interesting properties of MOFs impart various potential applications, such as gas adsorption and separation, hazardous substance adsorption and removal, proton conduction, chemical sensor, photoluminescence, and so on. Recently, photoluminescence properties of MOFs have become one of the research hotspots .…”
