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.
该化合物由式 1 表示。在式 1 中,X 是 O 或 S,R1 和 R2 独立地选自由芳基、杂芳基和-P(O)-R3R4 组成的组,其中芳基、杂芳基和-P(O)-R3R4 被选自由 (C1-C4)烷基、(C1-C4)烷氧基、芳基和杂芳基组成的组的 1 至 4 个取代基取代或未被取代。芳基 "指由 6 至 10 个环组成的基团,"杂芳基 "指由 5 至 14 个环组成的基团,这些环具有 1 至 4 个选自氧、硫和氮(包括季氮)的杂原子。R3 和 R4 独立选自芳基或杂芳基。
