Circular dichroism of graphene oxide: the chiral structure model

Abstract

We have observed the circular dichroism signal of dilute graphene oxide (GO), then systematically investigated the chirality of GO and established a probable chiral unit model. This study may open up a new field for understanding the structure of GO and lay the foundation for fabrication of GO-based materials.
