Abstract
Graphene has lots of applications, such as field-effect transistors, solar cells and transparent electrodes. In this work, we developed a new donor-acceptor graphene hybrid by covalently bonding a donor phenanthrene-9-carboxaldehyde (PCA) onto the acceptor graphene (PCA-graphene) via 1,3-dipolar cycloaddition azomethine ylides. The resulting PCA-graphene is soluble in N,N-dimethyformamide (DMF). The optoelectronic device (photoanode) fabricated by spin-coating DMF solution of the hybrids exhibits an enhanced photocurrent under visible irradiation.
