A bismuth(III) complex [(1,10-phen)Bi(C2O4)1.5]: Synthesis, crystal structure and optical properties

Synthesis, Characterization, and Photocatalytic Activity of Mixed-Ligand Cerium(III) and Bismuth(III) Complexes

“…6.4% weight loss in the temperature range of 412-650 °C. Such type of weight loss with two distinct degradation steps is in well agreement with the recent study of Huang et al, where two step weight loss was reported for the removal of organic ligands from the bismuth(III) complex ((1,10-phen)Bi(C 2 O 4 ) 1.5 ) [37]. e TGA curve became stable after 570 °C for complex 1 and 650 °C for complex 2; no further weight losses indicated the stability of the residues due to the formation of corresponding metal oxides [38].…”

Efficient Europium Sensitization via Low-Level Doping in a 2-D Bismuth-Organic Coordination Polymer

“…With respect to photoluminescent materials, early work by Vogler and colleagues proposed that Bi 3+ and the other main group metals with n s 2 electron configurations (e.g., Sb 3+ , Pb 2+ , Sn 2+ ) could undergo similar photochemistry and metal-to-ligand charge transfer (MLCT) transitions in the visible region as those displayed by d 10 metal ions. , Consistent with this notion, Bi 3+ has recently proven to be a promising candidate for luminescent materials. For example, in 2010 and 2011, zur Loye and colleagues published a series of solid-state coordination polymers containing Bi 3+ and 2,5-pyridinedicarboxylic acid (2,5-PDC) that displayed visible photoluminescence, with examples of blue, green, and even white light emission. − More recent examples of bismuth-organic coordination polymers have similarly exhibited blue, green, white, and yellow emission attributed to charge transfers, intraligand transitions, and s → p transitions of bismuth. − Bismuth-organic compounds have also displayed exciting properties including mechanochromism, , solvochromism, and polymorphism-dependent emission. , Furthermore, due to the similar oxidation states, ionic radii, and coordination geometries of Bi 3+ and Ln 3+ metal ions, bismuth-organic materials have been utilized as hosts for the trivalent lanthanides. Doping of Ln 3+ ions into bismuth-organic materials has yielded the highly desirable emissive properties of Ln 3+ ions while using just a fraction of the expensive rare earth starting materials relative to a homometallic Ln 3+ compound. − …”
