NOVELTY - A halogen-substituted compound (I), is new. USE - Halogen-substituted compound for manufacturing functionalized graphene oxide (claimed). ADVANTAGE - The halogen-substituted compound provides functionalized graphene oxide having excellent electroconductivity and dispersibility. DETAILED DESCRIPTION - A halogen-substituted compound of formula: (X)p-Ar-E-L (I), is new. X=F, Cl, Br or I; p=1-5; Ar=4-30C aryl or heteroaryl; L=-NH2, -SH, -OH, tosyl or -NHNH2;and E=linking group with Ar and L and chosen from 1-20C acyclic, cyclic or heterocyclic hydrocarbyl and 1-20C acyclic hydrocarbyl having carbonyl group. An INDEPENDENT CLAIM is included for manufacture of functionalized graphene oxide, which involves reacting the halogen-substituted compound and graphene oxide.
