light-emitting devices have the characteristics of high color purity， high luminous efficiency， and tunability in the visible light range. In recent years， they have shown great potential in lighting， display and other fields. However， the stability of perovskite quantum dot light-emitting diodes（PeQLEDs） is becoming the biggest obstacle to its commercial application. In addition to the stability of the perovskite light-emitting layer itself， the water-oxygen stability of the transport layer cannot be ignored. This work introduces a novel PeQLEDs that utilize an azole-based monomer-synthesized organic covalent polymer material（COP-N） instead of conventional PEDOT∶PSS as the hole injection layer material. We found that COP-N material has intrinsic water-oxygen stability， as well as a smaller hole injection barrier with PVK. These characteristics enable the COP-N-based PeQLED to achieve nearly twice the stability improvement while achieving better EQE than PEDO∶PSS. We believe that this organic covalent polymer material is expected to be a new type of hole injection material to achieve efficient and stable perovskite electroluminescent device， and promote the
