The invention belongs to the technical field of organic electroluminescence, and particularly relates to an oxazole derivative and application thereof in organic electroluminescence materials and light-emitting elements. When the oxazole derivative of the present invention is applied to an organic electroluminescent element as a material of a light-emitting layer, since the oxazole derivative has a higher carrier mobility than conventional materials, has high internal quantum efficiency, has excellent amorphous properties, and has a stable thin film state, the organic electroluminescent element has excellent light-emitting performance. The organic electroluminescent element can realize high efficiency, low driving voltage and long service life. 本发明属于有机电致发光技术领域，具体涉及一种噁唑衍生物及其在有机电致发光材料、发光元件中的应用。将本发明的的噁唑衍生物作为发光层的材料应用于有机电致发光元件时，由于噁唑衍生物的载流子迁移率比以往的材料大、具有高的内量子效率、具有优异的无定形性、并且薄膜状态稳定，因此，有机电致发光元件能够实现高效率、低驱动电压、长寿命。
