Cascading Electron Transfer In D-π-A Graphene Nanoconjugates

Background Introduction In 2004, Geim and Novoselov et al. first isolated a monolayer honeycomb network of graphene based on sp2-hybridized carbon atoms from graphite using mechanical exfoliation. Since then, due to its unprecedented physicochemical properties, such as high specific surface area (the theoretical specific surface area of monolayer graphene is 2630 m2 g-1), excellent thermal … Read more
