Patent number: 11345688Abstract: The compound is represented by Formula 1. In Formula 1, X is O or S, and R1 and R2 are independently selected from the group consisting of aryl, heteroaryl and —P(O)—R3R4, where the aryl, heteroaryl and —P(O)—R3R4 are substituted or unsubstituted with 1 to 4 substituents selected from the group consisting of (C1-C4)alkyl, (C1-C4)alkoxy, aryl and heteroaryl. The “aryl” means a group consisting of 6 to 10 cyclic rings, and the “heteroaryl” means a group consisting of 5 to 14 cyclic rings having 1 to 4 heteroatoms selected from oxygen, sulfur and nitrogen (including quaternary nitrogen). R3 and R4 are independently selected from aryl or heteroaryl.Type: GrantFiled: January 22, 2018Date of Patent: May 31, 2022Assignee: DAEGU GYEONGBUK INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Youn Gu Lee, Hong Gi Kim, Seok Hoon Jang
