Organic light emitting diodes (OLEDs) have been known for the next generation of display technology. In this work, we synthesized four benzo[d,e]chromene derivatives (BS01-BS04) varying the position of fluorine atom for OLED application. The compounds were characterized by 1H and 13C NMR, FTIR and mass spectroscopy. Their photoluminescence properties were studied which showed the thermally activated delayed fluorescence (TADF) character from intramolecular charged transfer (ICT) transition. The compounds were used as a dopant for OLEDs in the structure of ITO/NPB/BS01-BS04/Bphen/LiF/Al. The BS02 device exhibited green colour with the current efficiency at 1.28 cd/A and the power efficiency at 0.47 Im/W.
