We report the synthesis, photophysics and electrochemical properties of naphthalene-benzofuran compound 1 and its application in organic light emitting devices. Fluorescent deep-blue emitting devices employing 1 as the emitting dopant embedded in 4-4¡ä-bis(9-carbazolyl)-2,2¡ä-biphenyl (CBP) host show the peak external quantum efficiency of 4.5 % and Commission Internationale d¡¯¨¦nclairage (CIE) coordinates of (0.15, 0.07). Hybrid white devices using fluorescent blue emitting layer with 1 and a phosphorescent orange emitting layer based on an iridium-complex show the peak external quantum efficiency above 10 % and CIE coordinates of (0.31, 0.37).
