摘要： An organic compound represented by the formula [1]:
R1 to R19 are independently selected from the group consisting of a hydrogen atom, a deuterium atom, a halogen atom, and a substituent, and R9 and R19 are optionally bonded together. When R9 and R19 are bonded together, the bonding is selected from the group consisting of direct bonding, bonding via an oxygen atom or a sulfur atom, and bonding via CR20R21. R20 and R21 independently have the same meaning as R1 to R19. X1 and X2 independently denote an oxygen atom, a sulfur atom, CR20R21, or a single bond. Ar denotes an aromatic hydrocarbon group or a heterocyclic group, n denotes an integer in the range of 0 to 2, and m denotes an integer in the range of 1 to 4. When n is 0, any one of R1 to R8 is directly bonded to any one of R9 to R19.-
