The invention relates to a synthesis method and application of an asymmetric hole transport material 2BCz-sF. The asymmetric hole transport material 2BCz-sF containing carbazole, fluorene and spirofluorene groups with triphenylamine as a core structure is simple in synthesis route, short in synthesis time, easy in reaction, low in raw material cost, easy in separation and purification, suitable for large-scale preparation and suitable for industrial production. The hole transport material as a transition temperature can be in butt joint with a panel production line, the molecular symmetry is reduced, and the produced material has practical value and is an OLED display carrier transport material with good performance. 一种非对称型空穴传输材料的合成方法与应用，材料三苯胺为核心结构，含咔唑、芴和螺芴基团的非对称型空穴传输材料2BCz-sF，本发明合成路线简单，合成时间短，反应较容易进行，原料成本低廉，且易分离提纯，适合大量制备，作为转变温度的空穴传输材料可以与面板生产线对接，分子对称性的降低，生产的材料具有实用价值，是性能良好的OLED显示载流子传输材料。
