▎ 摘  要

NOVELTY - A graphene derivative (I) is new. USE - New graphene derivative is used for organic electroluminescence device (claimed). ADVANTAGE - The graphene derivative is efficiently prepared, by a simple process. DETAILED DESCRIPTION - A graphene derivative of formula (I) is new. A=group of formula (i); n=positive integer; X=-NO2 or -CN; R=-R1, -R2, -O-R1, -O-R2, -R1-C6H5, -R2-C6H5 or -R3; R1=5C or more alkyl; R2=substituted 5C or more alkyl;and R3=aryl. An INDEPENDENT CLAIM is included for organic electroluminescence device, which has an anode layer containing the graphene derivative.
