title: Nitrene addition to exfoliated graphene: a one-step route to highly functionalized graphene.
abstract: We demonstrate a high yield method of functionalizing graphene nanosheets through nitrene addition of azido-phenylalanine [Phe(N(3))] to exfoliated micro-crystalline graphite (microG). This method provides a direct route to highly functionalized graphene sheets. TEM analysis of the product shows few layer (n < 5) graphene sheets. The product was determined to have 1 phenylalanine substituent per 13 carbons.
