The non-emissive benzene ring and green-emissive arylmaleimide are employed as two independent cores to construct dual-core white star-shaped polymers (DC-PFMs). Due to the totally star-shaped structure, DC-PFMs display a higher quantum yield and electroluminescence efficiency for a more efficient energy transfer from the host to the guest than traditional single-core polymers (SC-PFMs).
