Recent progress in organic molecule/graphene interfaces

• We review recent progress on the studies of organic/graphene interfaces.
• Organic molecular assembly structure on graphene surface prepared on different substrates.
• Interfacial electronic properties between organic molecule and graphene.
• Outlook on the development and application of organic/graphene interface in organic devices.

SummaryGraphene holds great promise in wide-ranging applications due to its novel electronic, thermal, mechanical, and chemical properties. In many applications, graphene needs to be integrated with other materials, it is thus important to understand the surface physics and chemistry of graphene. Understanding the adsorption behavior of organic molecules on graphene is an important issue to develop the full potential of graphene-based organic electronic devices. This article reviews the interfacial morphologies and electronic structures between organic molecules and graphene, prepared on different substrates. Generally, adsorption of organic molecules on graphene exhibits two important characteristics: (1) formation of well-ordered organic layers based on the graphene template and (2) occurrence of charge transfer between adsorbed molecules and graphene, offering the promise in tuning the electronic properties of graphene.
