Research on graphene (Gr) is a vastly expanding field due to its potential for technological applications. Its close structural and chemical relationship to conjugated organic molecules makes it a superior candidate as a transparent electrode material in organic electronics and optoelectronics. The growth of organic thin films-intensively investigated in the past few decades-has demonstrated the complexity in growth and nucleation processes arising from the anisotropy and spatial extension of the molecular building blocks. Choosing the small, conjugated rod-like molecules para-hexaphenyl and pentacene as model representatives for small organic molecules, we review recent findings in organic thin film growth on a variety of Gr substrates. Special attention is paid to the differences in the resulting growth arising from the various methods of Gr fabrication and support that affect both the Gr-molecule interfacing and the involved molecular diffusion processes.
由于石墨烯（Gr）在技术应用方面的潜力，对其的研究是一个正在迅速扩展的领域。它与共轭有机分子在结构和化学上的紧密关系，使其成为有机电子学和光电子学中透明电极材料的理想候选者。在过去几十年中受到深入研究的有机薄膜生长，已证明了由于分子构建单元的各向异性和空间延伸而导致的生长和成核过程的复杂性。我们选择小的共轭棒状分子对六苯基和并五苯作为小有机分子的模型代表，回顾了在各种Gr衬底上有机薄膜生长的最新研究结果。特别关注了由于Gr制备和支撑的各种方法所导致的生长差异，这些方法会影响Gr与分子的界面以及相关的分子扩散过程。
