We use 4,4′-bipyridine as a prototypical molecule for these explorations as the energy level alignment of core-excited molecular orbitals allows ultrafast injection of electrons from a substrate to a molecule on a femtosecond timescale. We show that the ultrafast injection of electrons from the substrate to the molecule is ∼4 times slower on weakly coupled bilayer graphene than on epitaxial graphene. Through our experiments and calculations, we can attribute this to a difference in the density of states close to the Fermi level between graphene and bilayer graphene. We therefore show how graphene coupling with the substrate influences charge transfer dynamics between organic molecules and graphene interfaces.","lang":"eng"}],"status":"public","type":"journal_article","month":"03","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"closed access","author":[{"first_name":"Abhilash","last_name":"Ravikumar","full_name":"Ravikumar, Abhilash"},{"last_name":"Kladnik","first_name":"Gregor","full_name":"Kladnik, Gregor"},{"last_name":"Müller","first_name":"Moritz","full_name":"Müller, Moritz"},{"last_name":"Cossaro","first_name":"Albano","full_name":"Cossaro, Albano"},{"full_name":"Bavdek, Gregor","last_name":"Bavdek","first_name":"Gregor"},{"first_name":"Laerte L.","last_name":"Patera","full_name":"Patera, Laerte L."},{"first_name":"Daniel","last_name":"Sánchez-Portal","full_name":"Sánchez-Portal, Daniel"},{"orcid":"0000-0002-6957-6089","last_name":"Venkataraman","first_name":"Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha"},{"last_name":"Morgante","first_name":"Alberto","full_name":"Morgante, Alberto"},{"full_name":"Brivio, Gian Paolo","last_name":"Brivio","first_name":"Gian Paolo"},{"full_name":"Cvetko, Dean","first_name":"Dean","last_name":"Cvetko"},{"full_name":"Fratesi, Guido","first_name":"Guido","last_name":"Fratesi"}],"publication_identifier":{"issn":["2040-3364"],"eissn":["2040-3372"]},"language":[{"iso":"eng"}],"publisher":"Royal Society of Chemistry","issue":"17","oa_version":"None","article_processing_charge":"No","volume":10,"intvolume":"        10","quality_controlled":"1","title":"Tuning ultrafast electron injection dynamics at organic-graphene/metal interfaces","doi":"10.1039/c7nr08737c","publication_status":"published","article_type":"original","scopus_import":"1"}
