Abstract:
Disclosed herein is a composition for slowly releasing a fragrant molecule, including a complex of cucurbituril and a fragrant molecule. The composition is advantageous in that the fragrant molecule is more slowly released when it exists in the form of a complex compared to when it exists alone. Therefore, when a product including this complex is manufactured, the reduction of a fragrant material due to the long-term storage thereof can be minimized, and a fragrant material can be released for a long period of time compared to conventional products. Accordingly, it is presumed that this composition will be applied to air cleaning and environment improvement.
Abstract:
Provided are methods of storing and separating acetylene or oxygen using microporous metal formates having a three-dimensional structure of metal and formate ion (HCOO - ). Microporous metal formates used in the method selectively and stably adsorb a large amount of a specific gas within its structure. Therefore, those methods can be used in industrial appliances related to, for example, synthesis and transportation of high-purity gas.
Abstract:
A disubstituted cucurbituril-bonded silica gel and its use are provided. The disubstituted cu-curbituril-bonded silica gel is useful for removal of air pollutants or water contaminants, and separation and purification of biological, organic, inorganic, or ionic substances.
Abstract:
Disclosed herein is a composition for removing an odor molecule and releasing a fragrant molecule, the composition including a complex of cucurbituril and a fragrant molecule. The composition is characterized in that an odor molecule and a fragrant molecule are alternately bonded with cucurbituril, so the odor molecule is bonded with cucurbituril, and, simultaneously, the fragrant molecule is released from the complex. The composition provides very efficient air cleaning effects because it can exhibit both an odor removing effect and a fragrant molecule releasing effect using only cucurbituril which is a single-kind macrocyclic molecule.

Abstract:
Disclosed herein is a composition for removing odor, the composition including cucurbituril. The composition can capture and remove various kinds of odor materials (particularly, ammonium ion-containing bad odor, such as a fishy smell or the like) because cucurbituril can interact with various odor materials using its hydrophobic cavity and both inlets covered with carbonyl groups. Therefore, this composition can be practically applied to the cleaning of air and the improvement of an environment.
Abstract:
Provided is a method of separating cellular components, the method including: a) contacting a guest compound-bound reactive compound with cells; b) lysing the cells; c) adding a host compound-bound solid phase to a solution including the lysates of the cells to prepare a mixture; d) separating binding pairs of the guest compound bound to cellular components and the host compound bound to the solid phase from the mixture, and purifying the binding pairs; and e) separating the cellular components from the binding pairs, wherein the guest compound-bound reactive compound is obtained through a covalent bond between a reactive compound and a guest compound represented by Formula 2 below guest, the host compound-bound solid phase is obtained through a covalent bond between a solid phase and a host compound represented by Formula 1 below, and the reactive compound includes at least one selected from the group consisting of a biomolecule, N-hydroxysuccimide, an antigen, an antibody, an aptamer, folic acid, transferrin, and any mixtures thereof.
Abstract:
Provided are a stationary phase and a column using a cucurbituril-bound silica g el, and a method of separating taxane using the column. The taxane separation meth od includes: preparing a column for taxane separation, the column being packed with a stationary phase including a cucurbituril-bound silica gel in which a cucurbituril represen ted by Formula 1 or 2 is covalently bound to a modified silica gel represented by Formul a 3; dissolving a taxane powder in a solvent to prepare a taxane-containing solution; ap plying the taxane-containing solution to the column; supplying a mobile-phase solvent t o the column to obtain a taxane extract from the column; and purifying taxane from the t axane extract. Therefore, highly purified taxane can be separated from a low-purity cr ude taxane extract.
