Bi(iii) MOFs: syntheses, structures and applications

Abstract

Metal-organic frameworks (MOFs) are favored by researchers because of their high surface area, lofty porosity, excellent structural stability and diverse structures, and have been widely used in catalysis, sensing, adsorption,...

Harnessing Bismuth Coordination Chemistry to Achieve Bright, Long-Lived Organic Phosphorescence

“…Main-group-element-containing compounds, particularly those based on heavy-metal ions with n s 2 lone-pair electrons (e.g., Sn 2+ , Pb 2+ , Sb 3+ , and Bi 3+ ), are promising platforms for functional materials. Such materials have shown a range of nonlinear-optic, thermoelectric, and optoelectronic responses, as well as photophysical behavior. − In many cases, the unique chemical and physical properties of these main-group materials are derived from the metal-ion lone-pair electrons. , For example, the incorporation of asymmetric building blocks such as n s 2 metal ions with stereochemically active lone pairs is a powerful strategy for achieving noncentrosymmetric structures capable of second-harmonic-generation response. , Moreover, within n s 2 metal-ion halide perovskites, expression of the lone-pair electrons has been shown to result in highly anharmonic lattice dynamics that yield enhanced dynamic behavior, elevated dielectric response, and low thermal conductivity. ,, Such observations motivate current efforts to further understand, and indeed expand, structure–property relationships in main-group materials toward optoelectronic, quantum, and photophysical properties.…”

Sequential enhancement of proton conductivity by aliovalent cadmium substitution and post-synthetic esterolysis in a carboxylate-functionalized indium framework with dimethylaminium templates

“…3,4 Compared with other inorganic metal oxides or organic polymers, 5,6 metal-organic frameworks (MOFs) are studied and accepted as preferred candidates for next-generation conducting materials due to their ordered crystalline nature, high internal porosity and tunable modular functionality. [7][8][9][10] These unique characteristics are beneficial not only to acquire rich proton sources in a restricted volume to increase proton carrier concentration but also to create abundant hopping sites in a specific alignment to elevate the proton mobility. 11,12 Although most MOF materials show good prospects, it is still required to tactically fine-tune key structural components towards the precise design of high-level performance and long-term durability of proton conduction.…”

Dinuclear complexes, a one dimensional chain and a two dimensional layer of bismuth(iii) chalcogenones for C–S cross coupling reactions

“…Similarly, in 2 and 4, the hydroxyl (OH) groups (3.86 ppm for 2 and 3.48 ppm for 4) showed a 1 ppm downfield shift compared to free ligand L 2 (2.60 ppm). In 13 . This may be because metal coordination reduces the chalcogenone carbon (CQE) p-acceptance character.…”

“…12 Bi-MOFs can be synthesized using suitable bismuth salts, and organic ligands such as aromatic or aliphatic ligands consist of oxygen-containing functional groups like –OH, –COOH, –CHO, and –COOR. 13 Some of these materials were used as catalysts in photocatalytic degradation of Rhodamine B, 4 methyl orange degradation, 5 photocatalytic O 2 production, 6 photocatalytic hydrogen production, 7 CO 2 reduction, 8 ring-opening of ethylene oxide, 9 acetal formation, and esterification. 10 However, no reports are available in the literature on the use of imidazole chalcogenone ligands to synthesize Bi-CPs.…”
