Abstract |
|
|
|
Employing the multidentate ligands 1,2,3,4-tetra-(4-pyridyl)-butane (TPB) and
1,2,4-benzene tricarboxylic acid (H3BTC) as mixed bridges, a novel Cd(II) metal-organic framework was obtained and characterized by
single crystal X-ray diffraction, [Cd4(TPB)2(BTC3-)2(HBTC2-)(H2O)2·(H2O)]n (1). The three-dimensional (3-D) framework of complex 1 possesses three topologically nonequivalent nodes synchronously and
exhibits an unprecedented topology (445968)2(42536)(42537). And the complex
displays good thermal stability and strong photoluminescence in the blue region
band. Thus it may serve as a potential candidate of thermally stable
blue-light-emitting material.
