| Summary: | <p>Abstract</p> <p>The feasibility of edge-functionalization of graphite was tested via the model reaction between pyrene and 4-(2,4,6-trimethylphenyloxy)benzamide (TMPBA) in poly(phosphoric acid) (PPA)/phosphorous pentoxide (P<sub>2</sub>O<sub>5</sub>) medium. The functionalization was confirmed by various characterization techniques. On the basis of the model study, the reaction condition could be extended to the edge-functionalization of graphite with TMPBA. Preliminary results showed that the resultant TMPBA-grafted graphite (graphite-g-TMPBA) was found to be readily dispersible in <it>N</it>-methyl-2-pyrrolidone (NMP) and can be used as a precursor for edge-functionalized graphene (EFG).</p> |
