“…Only four permanently microporous MOFs (i.e. type I isotherms for N 2 ) have been successfully synthesized using Bi 3+ cations, to the best of our knowledge, including CAU‐7, NOTT‐220, CAU‐17 and CAU‐35 . All of these MOFs have only been discovered within the past five years, and relatively few detailed analyses of their properties and their potential applications have been reported.…”

“…All of these MOFs have only been discovered within the past five years, and relatively few detailed analyses of their properties and their potential applications have been reported. CAU‐7 has been described as a mild heterogeneous Lewis acid catalyst as demonstrated for the hydroxymethylation of 2‐methylfuran, and high gravimetric uptake of CO 2 and CH 4 was reported for NOTT‐220 . Of these four microporous bismuth MOFs, CAU‐17 is the only one that is synthesized using an inexpensive reagent for the organic linker: trimesic acid.…”

Very few microporous bismuth metal-organic frameworks have been discovered to date. Of these, no detailed experimental characterization of the synthesis and properties have been reported until now for the only one which can be prepared from inexpensive starting materials: CAU-17 [Bi(BTC)(H 2 O)], with H 3 BTC = trimesic acid. In-situ powder X-ray diffraction during solvothermal synthesis of CAU-17 revealed that it crystallizes rapidly within 2 minutes, and if the reaction is not stopped, the MOF transforms into a nonporous dense purely inorganic material within one hour, revealing that CAU-17 is a crystalline intermediate phase. Synthesis scale-up em- [a] 3496 ploying more concentrated reaction mixtures resulted in another Bi trimesate of composition [Bi(HBTC)(NO 3 )(MeOH)]· MeOH, which structurally decomposes upon storage under ambient conditions. Sorption experiments showed that CAU-17 is microporous with a BET surface area of 530 m 2 /g. As a potential greenhouse gas sorbent, CAU-17 showed high SF 6 /N 2 and CO 2 /N 2 selectivity > 31 and 29, respectively. Furthermore, the catalytic activity of CAU-17 was studied in the regioselective ring-opening of styrene oxide by methanol to obtain 2-methoxy-2-phenylethanol, thus demonstrating the existence of coordinatively unsaturated sites in the crystal structure of CAU-17.differ from structure to structure. Also, the large ionic radius of Bi 3+ ions [r (Bi 3+ ) = 1.31 Å, CN = 8] leads to highly complex and irregular coordination geometries around the Bi 3+ cations, which are often influenced by the 6s 2 lone pair of electrons. [18] Characterization of bismuth oxido clusters forming as metastable reaction products is a big challenge, as demonstrated in literature. [19]

We report the synthesis, structure, and photoluminescence properties of a new bismuth based luminescent metal−organic framework (LMOF). The framework is comprised of a 9-coordinated Bi 3+ building unit and 4′, 4‴, 4⁗′, 4⁗‴-(ethene-1,1,2,2-tetrayl)tetrakis([1,1′-biphenyl]-4carboxylic acid) (H 4 tcbpe) organic linker, which has strong yellow aggregation induced emission (AIE). The structure can be viewed as two interpenetrated 4,4-anionic nets that are stabilized by K + ions forming one-dimensional helical inorganic chains by connecting bismuth nodes through shared oxygen bonds. The as-made LMOF has a bluish emission centered at 459 nm with an internal quantum yield of 57% when excited at 360 nm. The emission properties of the LMOF were found to be highly solvochromic with respect to DMF. Upon partial solvent removal, the framework undergoes significant red-shifting to a greenish emission centered at 500 nm. Complete removal of DMF results in additional red-shifting fluorescence coupled with structural changes. The resulting material has strong blue-excitable (455 nm) yellow emission centered at 553 nm, with a quantum yield of 74%, which is maintained after heating in air for 5 days at 90 °C. This is the second highest quantum yield value for blue-excited yellow emission among all reported LMOFs.

“…Bismuth‐based CPs remain poorly explored, but become increasingly popular in a form of homoleptically enclosed metal centers due to their sufficiently broad range of potential applications. Therefore, some discrete complexes and CPs have been reported as potential bioactive (biocidic, antidiarrheal and antacid), or bioneutral compounds, gas sorption, luminescent and catalytic materials. In the absence of d‐ or f‐block electrons, Bi III ‐based compounds are transparent in the visible region of the electromagnetic spectrum, whose is highly desirable for its use as stable laser beam modulators, Q‐switches and mode‐lockers with the most spectrometers and devices equipped with laser source.…”

The novel 2D bismuth-camphorate IEF-1, formulated as [Bi(L)(HL)] (where H 2 L = camphoric acid), has been successfully isolated as large single crystals and easily scaled up by hydrothermal synthesis. The crystalline structure of IEF-1 was unveiled by single-crystal X-ray diffraction, in the monoclinic space group P2 1 , and fully characterized by using several standard solid-state techniques. IEF-1 material is thermally stable up [a] Advanced Porous
