The invention relates to an organic photoelectric material containing a ring-like urea structure and a preparation method and application thereof. The structure of the organic photoelectric material is as shown in the general formula (I). In the general formula (I), A is selected from one of the following structural groups: R1-R3 are separately selected from any one of hydrogen, methyl, ethyl, C6-C30 polycyclic aromatic group conjugated structural group or C4-C30 polycyclic aromatic group conjugated structural group containing hetero atoms such as N, S, O, etc. The organic photoelectric material containing a ring-like urea structure is applied to a CPL layer of an organic light-emitting device. The organic photoelectric material containing the ring-like urea structure has high glass-transition temperature and molecular heat stability, has low absorption and high refractive index in the field of visible light, can help promote light extraction efficiency of an organic light-emitting device effectively after being applied to the CPL layer of the organic light-emitting device, and has a good application effect and industrial prospects.
