Problems solved by technology

[0003] The 1,3-bis-4'-(3',5'-dimethyl)-pyrazole (also known as m-phenylpyrazole) ligand is rarely used to synthesize metal-organic complexes, but this ligand is Because the two pyrazole rings connected by the benzene ring have a certain twist angle and have certain flexibility, and the pyrazole ring has both a hydrogen bond acceptor atom (N) and a hydrogen bond donor group (N-H) , many coordination points and easy to form a hydrogen bond network in the system

Embodiment 1

[0025] CuCl 2 (0.1mmol), m-phenylpyrazole (0.05mmol) and ethanol (5mL) were added to a polytetrafluoroethylene autoclave, stirred at room temperature for 10min, then heated to 130°C at a rate of 5°C per hour, kept for 60h, and directly Cool to room temperature. Filtration and washing yielded a coordination polymer with a helical structure, with a yield of about 83%. Infrared spectral data (KBr, cm -1 ):3443 (m), 3236 (s), 2912 (w), 1582 (s), 1516 (s), 1439 (s), 1234 (m), 798 (s), 703 (s), 650 (s ), 609 (m).

[0026] Then the above-mentioned coordination polymer with helical structure was characterized

[0027] The crystal X-ray diffraction data were determined by Burkcer Smart CCD single crystal diffractometer. MoKa radiation (λ=0.71073 ?), graphite monochromator, data collected in ω-scan mode, with Lp factor correction and empirical absorption correction. First use the direct method to determine the position of metal atoms and some other non-hydrogen atoms, then use the...

Embodiment 2

[0033] CuCl 2 (0.12mmol), m-phenylpyrazole (0.05mmol) and ethanol (5mL) were added into a polytetrafluoroethylene autoclave, stirred at room temperature for 10min, then heated to 140°C at a rate of 4°C per hour, kept for 48h, and directly Cool to room temperature. Filtration and washing yielded a helical coordination polymer with a yield of about 78.3%.

Embodiment 3

[0035] CuCl 2 (0.1mmol), m-phenylpyrazole (0.06mmol) and ethanol (5mL) were added to a polytetrafluoroethylene autoclave, stirred at room temperature for 10min, then heated to 150°C at a rate of 3°C per hour, kept for 26h, and directly Cool to room temperature. Filtration and washing yielded a coordination polymer with a helical structure, with a yield of about 79.7%.

Description

technical field [0001] The invention relates to the field of inorganic chemistry, in particular to a two-dimensional coordination polymer and a preparation method thereof. Background technique [0002] In recent years, functional coordination polymers have become one of the important frontier directions in the field of material science due to their structural diversity and excellent functional properties. Coordination polymers generally refer to skeleton compounds with periodic network structures formed by self-assembly of metal ion centers and organic ligands, including one-dimensional (1D), two-dimensional (2D) or three-dimensional (3D) structures. It is different from simple complexes and general inorganic compounds or organic polymer compounds. It can contain a variety of metal ions and organic ligands, so it has a variety of types and special physical and chemical properties. The research on metal-organic coordination compounds spans many disciplines and categories suc...
