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.

“…Specifically, we reported the photoelectric and photocatalytic properties of a visible light responsive Bi-mna MOFs. 11 The The most interesting character of Bi-BTC is that there are two distinct 1D helix chains contained in the 3D structure along crystallographic b axis. As shown in Figure 2a, the 1D helix chain I is constructed by ligand BTC 3-2 and 4 connecting adjacent dimeric {Bi 2 O 14 } units in a symmetry of 2 1 along b axis.…”

A bismuth based metal-organic framework ([Bi(BTC)(DMF)]·DMF (CH3OH)2, Bi-BTC) with a novel topology structure is synthesized by a solvothermal method. Bi-BTC crystalizes in the P21/n space group, exhibits a novel 3D framework consisting of trimesic acid (H3BTC) linked with {Bi2O14} units and contains two helix chains which assemble regularly. In addition, we investigated the photophysical properties of Bi-BTC which shows high activity of O2 production in photocatalysis.

“…S4) show two individual peaks at 442.0 and 466.0 eV for BiBDC, which are assigned to Bi 4d 5/2 and Bi 4d 3/2 . This result indicates that Bi forms the hybrid BiBDC in its +3 valence state . Binding energies at 443.0 and 467.0 eV are observed for BiBDC‐Br(0.25) with an increased shift compared with BiBDC.…”

“…Additionally, Bi 3 + with geometrically flexible coordination environments with or without its active lone pair of electrons can act as an interesting node in the construction of organic–inorganic hybrids. MOFs based on bismuth carboxylates or analogues were reported to exhibit excellent properties such as gas adsorption and photocatalysis . And MOF‐based bismuth terephthalates have been applied in photoluminescence .…”

Halide anion-doped bismuth terephthalate hybrids were synthesized using a facile solvothermal method. Four series of hybrids doped with halide anions X À (F À , Cl À , Br À and I À ) were produced by varying the molar ratios (n) of X À relative to Bi (NO 3 ) 3 (n = 0.25, 0.5, 0.75 and 1) in dimethylformamide solution. The results indicated that 0.25 equiv. of different halide anion-doped bismuth terephthalate hybrids, especially BiBDC-Cl(0.25) and BiBDC-Br(0.25), exhibited excellent photocatalytic activity under visible light and UV light irradiation. They also exhibited excellent adsorption performance for Rhodamine B which could be attributed to high surface areas and negative charge on the surface of the catalysts. Moreover, the degradation of Rhodamine B under visible light irradiation is a photosensitization process andÀ is the most important active species. The halide anion-doped bismuth terephthalate hybrids are promising photocatalysts for removal of organic pollutants.
