Flexible Films of Covalent Organic Frameworks with Ultralow Dielectric Constants under High Humidity

Covalent organic framework (COF) films combine the processability of polymers with the porosity and atomic precision of crystalline porous materials, properties that are long-sought-after in electronics yet hard to realize. Herein, we prepared four flexib

Bipyridyl ligand and preparation method thereof, ruthenium supramolecular self-assembly body containing bipyridyl ligand and preparation method and application of ruthenium supramolecular self-assembly

The invention provides a novel bipyridyl bidentate ligand and a preparation method thereof. The structural formula of the novel bipyridyl bidentate ligand is shown in the specification. The inventionfurther provides a ruthenium supramolecular self-assembly body of the ligand and a preparation method of the ruthenium supramolecular self-assembly body. The preparation method comprises the followingsteps: putting a prepared ruthenium receptor and a bipyridyl ligand into a container, adding a mixed solvent of methanol and dichloromethane in equal proportion, stirring for a period of time at roomtemperature, spin-drying the solution to a certain volume after the reaction is finished, slowly adding diethyl ether, and separating out solid powder, namely the ruthenium supramolecular self-assembly body containing the bipyridyl ligand. The self-assembly body is a novel ruthenium-containing self-assembly compound, and has a good inhibition effect on cancer tumor cell lines A549 and HepG-2.
