Provided are a conjugated polymer containing ethynyl crosslinking group, mixture, formulation, organic electronic device containing the same and application thereof. The conjugated polymer material has a conjugated main chain structure and an ethynyl crosslinking group as a functional side chain. The conjugated polymer material produces an insoluble and unmeltable crosslinked interpenetrating network polymer film under heating, has excellent solvent-resistance, and is suitable for manufacturing a complex multi-layer organic electronic device. The conjugated polymer can be applied in optoelectronic devices such as an organic field effect transistor, an organic light emitting diode (OLED), a polymer solar cell, a perovskite solar cell, etc, and improves device performance.
