Organic molecule–two-dimensional material (OM–2D material) heterostructures are relatively an emergent class of hybrid-based electronic devices and yet have gained enormous interests. These systems hold promise towards application in the realization of electronic, optoelectronic and energy conversion devices, due to their tunable thickness, rich raw materials, flexibility, and also their capability to merge the high light absorption efficiency of organic molecules and the high carrier mobility of 2D materials. Dielectric screening effects have a large influence on electronic structure and optical properties at the OM–2D material interface due to the low intrinsic dielectric polarizability of both organic molecules and 2D materials. Here, we will review current knowledge about the dielectric screening behaviors in 2D materials and the screening effect at the OM–2D material heterointerfaces, including the physical origin of the dielectric screening effect across such interfaces, how to investigate it, and the influence of the screening effect on OM–2D material interfaces. Engineering of the dielectric screening effects in OM–2D material systems is also discussed. We conclude the review by illustrating a brief introduction of other important factors, e.g. defects, charge transfer, and hybridization, that will contribute to the screening effect and these features should be considered for the future scientific and device development of OM–2D material heterostructures.

有机二维材料异质界面的筛选效果

有机分子-二维材料（OM-2D 材料）异质结构是相对新兴的一类基于混合的电子器件，但已经获得了巨大的利益。这些系统具有可调节的厚度、丰富的原材料、柔韧性，以及将有机分子的高光吸收效率和高载流子迁移率相结合的能力，有望在电子、光电和能量转换器件的实现中得到应用。二维材料。由于有机分子和二维材料的低固有介电极化率，介电屏蔽效应对 OM-2D 材料界面处的电子结构和光学性质有很大影响。这里，我们将回顾当前关于 2D 材料中的介电屏蔽行为和 OM-2D 材料异质界面的屏蔽效应的知识，包括介电屏蔽效应在这些界面上的物理起源、如何研究它以及屏蔽效应的影响在 OM-2D 材料界面上。还讨论了 OM-2D 材料系统中的介电屏蔽效应工程。我们通过简要介绍其他重要因素（例如缺陷、电荷转移和杂化）来结束审查，这些因素将有助于筛选效应，并且这些特征应考虑用于 OM-2D 材料异质结构的未来科学和器件开发。包括跨这些界面的介电屏蔽效应的物理起源，如何研究它，以及屏蔽效应对 OM-2D 材料界面的影响。还讨论了 OM-2D 材料系统中的介电屏蔽效应工程。我们通过简要介绍其他重要因素（例如缺陷、电荷转移和杂化）来结束审查，这些因素将有助于筛选效应，并且这些特征应考虑用于 OM-2D 材料异质结构的未来科学和器件开发。包括跨这些界面的介电屏蔽效应的物理起源，如何研究它，以及屏蔽效应对 OM-2D 材料界面的影响。还讨论了 OM-2D 材料系统中的介电屏蔽效应工程。我们通过简要介绍其他重要因素（例如缺陷、电荷转移和杂化）来结束审查，这些因素将有助于筛选效应，并且这些特征应考虑用于 OM-2D 材料异质结构的未来科学和器件开发。
