[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] Notably, zur Loye and coworkers have reported a number of Bi coordination polymers and their fluorescence properties using pyridine dicarboxylate as ligand. [44][45][46][47][48] Stock, Cheetham and co-workers have also reported a small variety of interesting Bi-MOFs.…”

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.

“…[23,[38][39][40][41] MM-MOFs in which two different metals are presented in acertain proportion range have been reported to be prepared using synthetic procedures common in MOF synthesis,s uch as conventional heating and solvothermal procedures. [17,[42][43][44][45][46][47][48][49] Depending on the synthesis conditions and the nature and proportion of the various metal precursors the resulting MM-MOF can be derived from the thermodynamic or kinetic control and this may influence the distribution and location of the metals. Considering the possible differences,the synthetic procedures should screen av ariety of conditions,d etermining the influence of various parameters in the final MM-MOF.…”

“…[104] Stoichiometric MM-MOFs can catalyze various reactions such as cross condensation of benzaldehyde and cyclohexanone,c yclohexene oxidation, ring opening of styrene oxide where they have superior catalytic performance compared with homometallic MOFs. [44,105,106] In one of these examples, Co/Ni-MOF-74 was shown to be active in the oxidation of cyclohexene while no activity was observed for Ni-MOF-74. Theo bserved activity of Co/Ni-MOF-74 may be explained considering that Co substitutes Ni at those positions of Ni-MOF-74 where substrates have easy accessibility.F urthermore,the mixed-metal Co/Ni-MOF-74 MOF exhibited superior activity in the oxidation of cyclohexene compared to Co-MOF-74 possessing stoichiometric Co loading.…”

MOFs are synthesized following al arge variety of procedures,i ncluding solvo/hydro thermal methods,s low diffusion, conventional heating, slow evaporation, mechanochemical, and sonochemical. [28][29][30][31][32] Several of these synthetic Mixed-metal metal-organic frameworks (MM-MOFs) can be considered to be those MOFs having two different metals anywhere in the structure.H erein we summarizethe various strategies for the preparation of MM-MOFs and some of their applications in adsorption, gas separation, and catalysis.I ti sshown that compared to homometallic MOFs,MM-MOFs bring about the opportunity to take advantage of the complexity and the synergism derived from the presence of different metal ions in the structure of MOFs.This is reflected in as uperior performance and even stability of MM-MOFs respect to related single-metal MOFs.Emphasis is made on the use of MM-MOFs as catalysts for tandem reactions.

“…The title compound is the first heterometallic system having a bismuth carboxylate unit connected to a Cu II cation whose structure has been determined by X-ray crystallography. There is only one other example of a copper carboxylate that is connected to a Bi III cation; this system is a mixed-metal metal-organic framework (MOF) displaying a two-dimensional network that possesses catalytic activity (Shi et al, 2013).

In the linear coordination polymer catena-poly[[[aqua(1,10-phenanthroline-κ(2)N,N')copper(II)]-μ-pyridine-2,6-dicarboxylato-κ(4)O(2):O(2'),N,O(6)-[(nitrato-κ(2)O,O')bismuth(III)]-μ-pyridine-2,6-dicarboxylato-κ(4)O(2),N,O(6):O(6')] dihydrate], {[Bi(III)Cu(II)(C7H3NO4)2(NO3)(C12H8N2)(H2O)]·2H2O}n, the Bi(III) cation is O,N,O'-chelated by the two pyridine-2,6-dicarboxylate ligands and O,O'-chelated by the nitrate anion, the nine coordinating atoms conferring a tricapped trigonal prismatic environment on the metal centre. Each pyridine-2,6-dicarboxylate ligand uses one of its carboxylate O atoms to bind to an aqua(1,10-phenanthroline)copper(II) unit, the Cu-O dative bonds giving rise to the formation of a ribbon motif. The Cu(II) cation exhibits a square-pyramidal geometry. The ribbon motif propagates along the shortest axis of the triclinic unit cell and the solvent water molecules are hydrogen bonded to the same ribbon.
