  • Patent number: 11964930
    Abstract: An organic compound represented by formula [1]. In the formula rings Q represented by formula [1-1] are each independently present at positions *1 and *2 such that positions * of the rings Q correspond to the positions *1 and *2. The rings Q may be the same or different. R4 and R5 represent groups each independently selected from the group consisting of a hydrogen atom and a substituted or unsubstituted aryl group. The rings Q are aromatic hydrocarbons. R1 to R3 represent groups each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and a cyano group. At least one of R1 to R3 represents a cyano group.
