(TADF) emitters with high efficiency still remain a difficulty in the field of organiclight-emittingdiodes (OLEDs). The key issue lies in the contradiction between red-shifting emission spectra and retaining high photoluminescence quantum yields (PLQYs). To tackle this problem, TADF-assisted fluorescent OLEDs (TAF-OLEDs) are one promising method. In this work, two charge-transfer (CT) fluorescent emitters
