The present invention relates to a method for manufacturing a graphitic carbon nitride-polystyrene complex and an organic electroluminescent device (OLED) comprising the method for manufacturing the graphitic carbon nitride-polystyrene complex. The method for manufacturing graphitic carbon nitride according to an embodiment comprises following steps of: preparing a graphitic carbon nitride precursor; conducting a first heat treatment of the graphitic carbon nitride precursor while supplying water thereto; conducting a secondary heat treatment of the graphitic carbon nitride under an inert atmosphere; and mixing the graphite carbon nitride subjected to the secondary heat treatment with a polymer. The present invention can manufacture graphitic carbon nitride and the graphitic carbon nitride-polystyrene complex in a simple method by mixing the graphitic carbon nitride with polystyrene.
