Patent number: 9433234Abstract: 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.Type: GrantFiled: November 15, 2013Date of Patent: September 6, 2016Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Kimoon Kim, Young Ho Ko, Su Hyun Lee, Selvapalam Narayanan, Don Wook Lee

Publication number: 20150297772Abstract: 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 alternately make a complex with cucurbituril, so the odor molecule makes a complex 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.Type: ApplicationFiled: November 15, 2013Publication date: October 22, 2015Applicant: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Kimoon KIM, Young Ho KO, Su Hyun LEE, Selvapalam NARAYANAN, Don Wook LEE
