Describes electrochemical formation of Hyperstage-1 graphite intercalation compound (GIC) from HOPG using tetrabutylammonium (TBA+) intercalation in acetonitrile/DMF solvent mixture with a continuous potential ramp. The Hyperstage-1 GIC (interlayer spacing >15.3 Å) undergoes spontaneous exfoliation upon reaction with 3,5-dinitrobenzenediazonium tetrafluoroborate to produce soluble functionalized graphene with 3,5-dinitrophenyl (3,5-DiNP) groups at a ratio of approximately one pendant aromatic ring per 12 graphene carbons. GIC stages were characterized by XRD, Raman spectroscopy, and the functionalized graphene showed high dispersibility (~0.24 mg/mL) in DMF and capacity for Meisenheimer complex formation with n-butylamine.
