摘要：The electron interaction among the noncovalently engineered graphene-methylene blue（MB） nanocompo- site with a dipolar pull-push hybrid model was studied. The π-π interaction between reduced graphene oxide（rGO） and MB molecule was studied by 1HNMR spectroscopy. The electrochemical investigation indicates MB has a stronger electron transfer interaction with rGO than with GO. The ability of graphene-MB nanocomposites to undergo photoinduced electron transfer was confirmed from the capability of the nanocomposites coated electrode to generate photocurrent in a photoelectrochemical cell. The role of graphene as electron acceptor in the opto-electronic assembly was discussed.
