Abstract: Provided are a polymer capsule loaded with transition metal particles having excellent water dispersibility and stability, and a method for preparing the same. Specifically, the polymer capsule loaded with transition metal particles according to the present invention includes a surface-modified polymer capsule surface-modified to thereby have a positive zeta potential in a dispersed state in water; and transition metal particles loaded on a surface of the surface-modified polymer capsule. In addition, a method for preparing a polymer capsule loaded with transition metal particles according to the present invention includes a) preparing a polymer capsule; b) surface-modifying the polymer capsule to prepare a polymer capsule having a positive zeta potential in a dispersed state in water; and c) sequentially adding a water-soluble transition metal precursor and a reducing agent to a water dispersion of the surface-modified polymer capsule obtained in step b).

Abstract: Provided are a transition metal compound including a novel carbene compound as a ligand, a preparation method thereof, and an application thereof. The transition metal compound according to the present invention may form a structurally stable complex and also have a HOMO-LUMO energy gap and singlet-triplet transition energy which are significantly low as compared with a conventional transition metal compound. In addition, according to the present invention, the transition metal compound may be synthesized in large quantities by a very simple method, thereby having high commercial utility, and thus, an application using the compound is expected.

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 translation: 本文公开了用于除去气味的组合物，该组合物包括葫芦素。 由于葫芦巴可以使用其疏水腔和两个入口被羰基覆盖，因此可以捕获并除去各种气味物质（特别是含有铵离子的不良气味，如鱼腥味等）。 因此，该组合物可以实际应用于清洁空气和改善环境。
