To provide an organic compound that allows red emission with high color purity in a long wavelength region by a basic skeleton itself.SOLUTION: The present invention provides an organic compound illustrated by general formula [1]. In general formula [1], Rto Rare independently selected from a hydrogen atom, a halogen atom or a substituent. At least two of Rto Rbind to each other to form a ring structure. Of Rto R, one not forming the ring structure is selected from a hydrogen atom or the substituent.SELECTED DRAWING: Figure 1 【課題】 基本骨格自体で長波長領域における色純度の高い赤色発光が可能な有機化合物を提供する。【解決手段】 本発明は、下記一般式［１］で表されることを特徴とする有機化合物を提供する。一般式［１］において、Ｒ１乃至Ｒ２２は、水素原子、ハロゲン原子または置換基からそれぞれ独立に選ばれる。Ｒ１２乃至Ｒ１４の少なくとも２つは、互いに結合して環構造を形成する。Ｒ１２乃至Ｒ１４のうち、前記環構造を形成しないものは、水素原子または前記置換基から選ばれる。【選択図】 図１
