Pure white-light and yellow-to-blue emission tuning in single crystals of Dy(iii) metal–organic frameworks

Abstract

Direct white-light emission was first achieved in a single phase material of a Dy(III) metal-organic framework, which also shows tunable yellow-to-blue photoluminescence upon variation of excitation wavelengths.

Three d10 metal coordination compounds based on pyrazole-3-carboxylic acid showing mixed-ligand characteristic: Syntheses, crystal structures, and photoluminescent properties

“…On the other hand, among the various applications of MOCCs as stated above, the photoluminescence of MOCCs and its related applications [35][36][37][38][39] e.g., the white-light emitter and fluorescence sensor attract more attention from scientists [40][41][42][43][44][45]. Take d 10 Zn(II) and Cd(II) ions for example, they can form coordination geometries varying from tetrahedron, trigonal-bipyramid and square-pyramid to octahedron, hence are suitable for constructing interesting photoluminescent MOCCs with diverse structures [35,36].…”

3D Microporous Lanthanide–Organic Frameworks Constructed from Left‐ and Right‐Handed Helical Chains: Synthesis, Crystal Structure, and Tunable Photo­luminescence

“…[5,6] The most interesting examples of luminescent MOFs are lanthanide(III) (Ln III ) complexes because of their high quantum yield, large Stokes shift, and long emission lifetimes. [13][14][15][16][17][18][19][20][21][22][23][24] Therefore, Ln III -doped materials are of great interest for tunable luminescence. In particular, Eu III /Tb III -containing complexes are the most intense emitters among those of the lanthanide series.…”

“…Interestingly, Ln III doping can improve the luminescence property of the Ln III com-plexes and achieve white-light emission. [13][14][15][16][17][18][19][20][21][22][23][24][31][32][33][34] Our strategy is to develop luminescent LnOFs that consist of Ln III ions and organic ligands. [25] We are interested in exploring white-light-emitting materials based on MOFs, because white-light emitting materials can be widely used in displays and lighting.…”

Two novel pillar-layered Mn(II) coordination networks based on aromatic carboxylic acids with aminodiacetate functionality

“…Magnetism studies indicate that two complexes both exhibit dominant antiferromagnetic behaviors. In addition, the fitting of magnetic susceptibility (χ M ) of 1 is performed based on the model of the alternating -J 1 J 2 -coupling chain and considering molecular-field approximation.An ever increasing research work has been devoted to the design and construction of coordination networks due to numerous fascinating architectures and great potential applications as solid functional materials [1][2][3][4][5][6][7][8]. A number of various coordination networks with defined structural motifs have been designed and synthesized successfully by the judicious selection of metal ions and organic ligands with definite coordination preferences [9-15].…”
