The invention relates to an organic photoelectric material with a carbazole and iminostilbene structure and application of the organic photoelectric material. A compound structural formula of the organic photoelectric material is as shown in the specification, wherein Ar1 is selected from one of phenyl, phenylalkyl with carbon number being 7-14, polycyclic conjugate aryl with carbon number being 10-60 and aromatic heterocyclic radical containing at least one of N, S and O. The organic photoelectric material which is an OLED (organic light emitting device) material is high in thermal stability and excellent in hole transport capacity and can serve as a hole transport layer of an organic light emitting device to remarkably improve efficiency of the device. 本发明涉及种含有咔唑和亚氨基芪结构的有机光电材料及其应用，所述有机光电材料的化合物结构式通式如下式所示：其中，Ar选自苯基、碳原子数位7～14苯烷基、碳原子数为10～60的多环共轭芳基、以及含有N、S、O中的至少种的芳族杂环基中的种。本发明提供的OLED材料的热稳定性好，具有良好的空穴传输能力，用作有机电致器件的空穴传输层，可显著提高器件的效率。
