Polycyclic aromatic hydrocarbons (PAHs) have become one of the essential types of materials for organic electronics and bio-photonics, such as organic field-effect transistors, organic solar cells, bio-imaging, and cancer therapy. Acenaphthylene-imide (AnI)-fused PAHs with the inherent large π-conjugated framework and electron-deficient imide moiety endow molecules low-lying LUMO energy levels for n-type organic semiconductors. In this review, the recent development of AnI-fused PAHs as organic semiconductors will be summarized, the synthetic methodology and the relationship between the molecular structures and properties (photophysical properties and/or devices performances) will be discussed in details. And it is believed to be helpful for further molecular design of AnI-fused PAHs with novel topological structures as functional materials.

多环芳烃（PAH）已成为有机电子和生物光子学材料的基本类型之一，例如有机场效应晶体管，有机太阳能电池，生物成像和癌症治疗。具有固有的大π共轭骨架和缺电子的酰亚胺部分的Ac乙烯-酰亚胺（AnI）熔合的PAH为n型有机半导体提供了较低的LUMO能级分子。在这篇综述中，将概述作为有机半导体的AnI熔合PAHs的最新发展，将详细讨论合成方法以及分子结构与性质（光物理性质和/或器件性能）之间的关系。据信这对进一步设计分子结构是有帮助的。具有新型拓扑结构的AnI融合PAHs作为功能材料。
