- Facile preparation of polytopic azoles: Synthesis, characterization, and X-ray powder diffraction studies of 1,4-bis(pyrazol-4-yl) and 1,4-bis(tetrazol-5-yl)benzene
-
Two polytopic azoles, 1,4-bis(pyrazol-4-yl)benzene and 1,4-bis(tetrazol-5- yl)benzene, were prepared in sizable amounts by high yield syntheses employing, in mild conditions, cheap reactants and, whenever possible, aqueous solutions. The two species were

- Preparation method of pyrazole-4-aryl derivative
-
The invention discloses a preparation method of a pyrazole-4-aryl derivative. The preparation method comprises the following step: mixing an aryl halide derivative, a pyrazole-4-boronic acid pinacol ester derivative, first alkali, a first phase transfer catalyst and a first palladium-based catalyst in a first solvent to carry out reaction so as to prepare the pyrazole-4-aryl derivative. Through the manner, the pyrazole-4-aryl derivative is prepared through the adoption of a one-pot method; the reaction condition is mild and the post-treatment is simple and convenient, so that the method is suitable for multiple aryl halide derivatives, strong in operability and suitable for industrial production; and the obtained pyrazole compound can be widely applied to the field of chemical engineering,medicines, biology and materials.

- Highly hydrophobic isoreticular porous metal-organic frameworks for the capture of harmful volatile organic compounds
-
Tunable hydrophobicity: Efficient air filters for the protection against chemical warfare agents might be achieved by surface functionalization of the pores in robust metal-organic frameworks (MOFs) with fluoroalkyl residues and the precise control of their pore size (see picture). These MOFs capture harmful volatile organic compounds even under extremely moist conditions (80 % relative humidity). Copyright
