摘　　要：基于光致异构分子构筑单分子光电子器件或分子膜器件,探究器件中分子在光诱导下构型的变化规律,并在单分子水平上探索其异构效应对电荷传输、器件光电性能的影响,对推动有关分子器件的基础应用研究至关重要.本文系统阐述近些年关于光致异构分子器件的研究成果,着重梳理了关于分子器件的制备、电荷传输机理、器件性能调控以及应用等方面的代表性进展,为未来开发功能性分子器件以及实现复杂集成电路或计算系统应用提供一定的思路.The study of molecular configuration transitions is crucial to the basic and application research of molecular devices, including the construction of single-molecule optoelectronic devices or molecular film devices based on photoisomerized molecules, the detection of light-induced molecular configuration changes at the single-molecule level and the exploration of their effects on the charge transport and the photoelectric performance of the devices. This article systematically describes the research of photoisomerization-molecular devices in recent years, and summarizes a series of representative developments in molecular device preparation, charge transport mechanism, device performance control and applications. It also provides certain ideas for the further development of functional molecular devices and the realization of complex integrated circuits or computing system in the future.
