Graphene derivatives

List of graphene derivatives prepared on the basis of chemistry of fluorographene. Additional information about fluorographene chemistry, properties and applications can be found in our recent review in Appl. Mater. Today.

Name Functional Group Description Reference
Hydroxofluorographene F, OH Various hydroxofluorographenes CxFy(OH)z can be prepared by treatment of FG with bases B(OH). These materials display magnetic ordering depending on their composition. One of them is room temperature antiferromagnet. Nat. Commun., 8, 14525 , 2017
Thiofluorographene F, SH It can be prepared by reaction of FG with NaSH. It was used for impedimetric sensing. Adv. Mater., 27(14), 2305-2310, 2015
Cyanographene (graphene nitrile) CN This is hydrophilic material with 15% of degree of functionalization. It was prepared by reaction of FG with NaCN. Thermally stable to ~120 °C. ACS Nano, 11(3), 2982–2991, 2017
Graphene acid (graphene carboxylic acid) -COOH Acidic hydrolysis of cyanographene results to graphene-acid. Water dispersible graphene derivative having nice titration curve, pKa 5.2. ACS Nano, 11(3), 2982–2991, 2017
