Abstract

The present invention relates to a 2-substituted rubrene compound represented by formula (I), characterized in that R1 represented by formula (I) is a formyl group, which is 2-formylrubrene, and 2-formyl red Uses of fluorene, and method for synthesizing the same. Using 2-formylrubrene as raw material, other 2-substituted rubrene compounds were synthesized through oxidation, reduction and condensation reactions. As a novel red fluorescent material, the compound of the present invention has high fluorescence quantum efficiency, and can be used as a material for the light-emitting layer in an electroluminescent device.
