Abstract:
PURPOSE: Rubber gloves forming bubbles are provided to actively form cleanser foam without any separate loofah, prevent the waste object from sliding and being separated, and the end portion of the rubber gloves is steadily fixed to the arms when using it. CONSTITUTION: The rubber gloves forming bubbles comprises a glove unit (100) formed in a glove shape corresponding to the hand of the user and an arm warmer unit (200) formed to cover the portion of the arm by extended from the end portion of the glove portion. The glove unit prevents the waste object from sliding by forming a protrusion on the external portion corresponding to the palms of the users and has multiple bubble protrusions (110) which forms the bubble by having multiple fine holes (111) to the detergent element and water go in and out.
Abstract:
A supramolecular capsule for ammonium ions is provided to transport selectively ammonium ions by binding them in a cavity and control package, transport and release of ammonium ions through self-assembly and disassembly itself. Precursors of supramolecular capsule for ammonium ions are represented by the formula(1), wherein R is methyl or ethyl; a nitrogen of pyridine group coordinately binds with a transition metal; and a nitrogen of phenyl oxazoline group forms a hydrogen bonding with hydrogen of ammonium ions. A supramolecular capsule for ammonium ions as a dimmer of the precursors of supramolecular capsule for ammonium ions is represented by the formula(2), wherein X is a transition metal and R is methyl or ethyl. The supramolecular capsule for ammonium ions is self-assembled by mixing the precursors of supramolecular capsule for ammonium ions with a trans type transition metal complex in a solvent selected from solvents having dipole moment of 2.91D or less and its mixture, wherein the transition metal is palladium, and the solvent having dipole moment of 2.91D or less is dichloromethane, chloroform or acetone. The supramolecular capsule for ammonium ions is disassembled by adding triethyl amine into the supramolecular capsule for ammonium ions.
Abstract:
A receptor of dopamine is provided to improve selectivity and binding properties to dopamine in neutral pH buffer solution, so that it is useful for detecting dopamine in aqueous solution and blood or promoting activity of dopamine in blood. A receptor of dopamine represented by the formula(1) is provided, wherein R is methyl or ethyl, and R' is O(CH2)4SO3^-Na^+. A nitrogen atom of phenyl oxazoline substituent of the dopamine receptor forms a hydrogen bonding with an ammonium ion of dopamine; a benzene ring of the dopamine receptor forms the cation-pi interaction with an ammonium ion of dopamine. An ether bonding or an oxygen atom of a butanesulfonate group of the dopamine receptor forms a hydrogen bonding with a catechol hydroxy group of dopamine. A phenyl group of the dopamine receptor forms the pi-pi interaction with a benzene ring of dopamine. A method for producing the dopamine receptor comprises the steps of: (a) reacting aminoalcohol represented by the formula(2) with triacid represented by the formula(3) to prepare compounds represented by the formula(4); (b) substituting OR' of compounds represented by the formula(4) by OH of a base to prepare compounds by the formula(5); and (c) reacting the compounds represented by the formula(5) with 1,4-butanesultone under basic conditions. In the formulae(2)-(5), R is methyl or ethyl and R' is TBS(tert-butyldimethylsilyl).
