Synthesis of graphene soluble in organic solvents by simultaneous ether-functionalization with octadecane groups and reduction

Octadecane-functionalized graphene (OD-G) soluble in organic solvents was produced by combining the 21 Hummers process for graphite oxidation and a simultaneous ether-functionalization and reduction approach 22 with 1-bromooctadecane in pyridine and dimethylformamide (D...
