Opto-electronic multifunctional chiral diamondoid-network coordination polymer: bis{4-[2-(4-pyridyl)ethenyl]benzoato}zinc with high thermal stability

Abstract

A novel 8-fold interpenetration diamondoid-like chiral condensed neutral coordination polymer, bis{4-[2-(4-pyridyl)ethenyl]benzoato}zinc [Zn(PEBA) 2 ] 1, synthesized by the hydrothermal reaction between Zn(ClO 4 ) 2 •6H 2 O and 4-[2-(4-pyridylethenyl)]benzenecarbonitrile (PEBC), displays very strong blue fluorescent emission and SHG response (ca. 1.5 3 that of urea) as well as high thermal stability (up to ca. 430 °C).

Synthesis, crystal structure and luminescent property of the novel μ-thiocyanato-bis[(2-acetylpyridinethiosemicabazonato)(thiocyanate)] cadmium(II) complex

“…In addition to being robust and thermally stable, some exhibit photoluminiscent properties, a feature that has contributed to d 10 metal polynuclear complexes being investigated in search for new materials [4][5][6]. Most of the Cd(II) coordination polymers featuring interesting supramolecular structures, such as one dimensional helical ribbon or molecular zippers, two dimensional molecular squares or triangular grids, and penetrating and non-penetrating three dimensional networks [7][8][9] possessing photoluminescent properties [10,11]. Owing to the versatile coordination mode of the ambidentate thiocyanate ligand, this pseudo halide ligand has become one of the most extensively studied building blocks in multidimensional complexes [12,13].…”

Synthesis, crystal structure, and luminescent properties of metal complexes bearing 2,6-pyridine-diacylhydrazide ligands: supramolecular assemblies via intermolecular interactions

“…The complexes exhibit characteristic luminescence with maximum at 485 nm upon excitation at 396 nm for 2 and 476 nm upon excitation at 397 nm for 3, respectively, which are assigned to intraligand transitions. These emissions are slightly disturbed by the coordination of H 4 L 2-to metal ions [40]. The emission decay profiles of complexes 2 and 3 in the solid state were obtained at room temperature.…”

Synthesis, crystal structure and magnetic properties of a new 3D coordination polymer constructed by Co(II) with pyridine-3,4-dicarboxylate and 4,4’-bipyridine

“…One of the attractive challenges in this field is the construction of chiral coordination frameworks. Several approaches were previously reported for creating chiral polymeric coordination frameworks, including the introduction of chiral or achiral building blocks [12]. Among them, unlike the square-planar Pt or Pd complexes, octahedral Co(II) or Mn(II) complexes with chelating ligands are inherently chiral [13].…”
