Click-assembled N-graphene–C60 hybrids for ultrafast electron transfer

A novel donor–acceptor hybrid derived from N-doped graphene (NG) and an electron acceptor, C60, has been newly synthesized using click chemistry and characterized by a suite of physico–chemical techniques. The usage of click chemistry resulted in a relatively high degree of functionalization. Due to...
